99:59:59.999 --> 99:59:59.999
Today, I talk about FAI.me, which is a
build for images.

99:59:59.999 --> 99:59:59.999
First, anybody that never heard anything
about FAI?

99:59:59.999 --> 99:59:59.999
Ok

99:59:59.999 --> 99:59:59.999
I started this project in 1999.

99:59:59.999 --> 99:59:59.999
I'm not sure…

99:59:59.999 --> 99:59:59.999
No, I'm sure that during those times, the
Debian installer did not have

99:59:59.999 --> 99:59:59.999
the preseeding stuff, so we needed
something automatically.

99:59:59.999 --> 99:59:59.999
I installed the first cluster with FAI and
I always do talks on FAI or

99:59:59.999 --> 99:59:59.999
today in the lightning talks, I talk
a little bit about dracut,

99:59:59.999 --> 99:59:59.999
which is used in FAI.

99:59:59.999 --> 99:59:59.999
So, what was the motivation.

99:59:59.999 --> 99:59:59.999
A neighbour of mine, she came to me with

99:59:59.999 --> 99:59:59.999
"My Windows desktop is broken,
can you reinstall it?"

99:59:59.999 --> 99:59:59.999
And in the end, I installed her Linux,
and I was shortly thinking about

99:59:59.999 --> 99:59:59.999
"Should I use FAI for installing her
desktop with Linux?"

99:59:59.999 --> 99:59:59.999
And in the end, I did not use it because
FAI is too complicated,

99:59:59.999 --> 99:59:59.999
like the Debian installer, I guess it's
not really that easy for beginners

99:59:59.999 --> 99:59:59.999
because there are a lot of questions

99:59:59.999 --> 99:59:59.999
but also FAI is not really for beginners.

99:59:59.999 --> 99:59:59.999
So this was the motivation about thinking
about FAI.

99:59:59.999 --> 99:59:59.999
The target group was always advanced
sysadmins

99:59:59.999 --> 99:59:59.999
but I thought maybe it's possible to make
FAI usable also for people

99:59:59.999 --> 99:59:59.999
that are not that advanced sysadmins.

99:59:59.999 --> 99:59:59.999
The idea is that an installer should cover
most installations.

99:59:59.999 --> 99:59:59.999
The Debian installer is really perfect
because I think it covers

99:59:59.999 --> 99:59:59.999
all different kinds and strange environments

99:59:59.999 --> 99:59:59.999
You can do a lot of things, you can configure
very strange combination of language,

99:59:59.999 --> 99:59:59.999
keyboard layout and so on

99:59:59.999 --> 99:59:59.999
but I was thinking about an installer
that covers 90 or 95% of the installations

99:59:59.999 --> 99:59:59.999
A lot of special cases can be ignored and
since the Debian installer has like

99:59:59.999 --> 99:59:59.999
more than 20 questions, I thought it would
be much nicer if there were only

99:59:59.999 --> 99:59:59.999
3 to 5 questions and I looked at Linux Mint
and Mageia installers, CentOS installer,

99:59:59.999 --> 99:59:59.999
and they all ask much less questions.

99:59:59.999 --> 99:59:59.999
In the Debian installer, we sometimes
have also things that are asked

99:59:59.999 --> 99:59:59.999
during the installation, so not everything
is asked at the very beginning.

99:59:59.999 --> 99:59:59.999
For example, the task selection, where you
select your desktop,

99:59:59.999 --> 99:59:59.999
is done after the base installation.

99:59:59.999 --> 99:59:59.999
This was also very important, I would like
to have something that

99:59:59.999 --> 99:59:59.999
asks everything at the very beginning.

99:59:59.999 --> 99:59:59.999
Then, maybe some tool could create
a customized installation image

99:59:59.999 --> 99:59:59.999
and this installation image should run
then completely unattended

99:59:59.999 --> 99:59:59.999
so you can get yourself a coffee and
when you come back, your machine is ready.

99:59:59.999 --> 99:59:59.999
There are 3 things to customize installation
image,

99:59:59.999 --> 99:59:59.999
you just put this image, you do not have
to touch anything, and then it's ready.

99:59:59.999 --> 99:59:59.999
I thought "Oh yes, this is FAI, maybe
FAI can do this."

99:59:59.999 --> 99:59:59.999
As I said, FAI is only, or was until now
only a tool for experienced sysadmins

99:59:59.999 --> 99:59:59.999
and you have to adjust several config
files, these are ASCII files

99:59:59.999 --> 99:59:59.999
but still you have to touch 5 to 10
config files to make a customization.

99:59:59.999 --> 99:59:59.999
So, how can I make FAI usable for
beginners?

99:59:59.999 --> 99:59:59.999
That's the beginning of FAI.me.

99:59:59.999 --> 99:59:59.999
There's a web page, we'll show it
in more detail later,

99:59:59.999 --> 99:59:59.999
where you can just click some things, and
then you get a customized image.

99:59:59.999 --> 99:59:59.999
This image can be put onto a CD, DVD or
USB stick, just with dd

99:59:59.999 --> 99:59:59.999
and the customization is just by using
the web interface

99:59:59.999 --> 99:59:59.999
so there's no need for you to edit
a text file, a config file inside FAI.

99:59:59.999 --> 99:59:59.999
I hope I covered most important thangs
that you want to adjust

99:59:59.999 --> 99:59:59.999
or a little bit customize.

99:59:59.999 --> 99:59:59.999
You can add additional packages, I think
that's the most important thing

99:59:59.999 --> 99:59:59.999
that people say "I want to have the normal
Debian installation

99:59:59.999 --> 99:59:59.999
but with some additional packages."

99:59:59.999 --> 99:59:59.999
And you can select different different
distributions, so it's not only

99:59:59.999 --> 99:59:59.999
the installation image for the stable
release, you can create

99:59:59.999 --> 99:59:59.999
3 variants of the installation.

99:59:59.999 --> 99:59:59.999
This is the web page and thanks to Juri,
he did a great job

99:59:59.999 --> 99:59:59.999
during the first and second day, he added
a new feature that we now have

99:59:59.999 --> 99:59:59.999
a toggle button.

99:59:59.999 --> 99:59:59.999
Is it big enough or should I zoom in?

99:59:59.999 --> 99:59:59.999
Ok.

99:59:59.999 --> 99:59:59.999
So, we have a toggle button, what you see
now is just the bare minimum or questions

99:59:59.999 --> 99:59:59.999
and we can toggle it to more advanced
settings.

99:59:59.999 --> 99:59:59.999
You have to select or just leave this as
it is, username,

99:59:59.999 --> 99:59:59.999
if you do not enter a password, a password
will be generated and shown to you

99:59:59.999 --> 99:59:59.999
and sent by e-mail.

99:59:59.999 --> 99:59:59.999
I will now just type in the password.

99:59:59.999 --> 99:59:59.999
It's here in clear text, for me that's fine
because

99:59:59.999 --> 99:59:59.999
there's also a comment that you should
change the password after the installation

99:59:59.999 --> 99:59:59.999
and I do not like to enter passwords twice
so you can see what you typed in

99:59:59.999 --> 99:59:59.999
and hopefully do not make any wrong
mistakes.

99:59:59.999 --> 99:59:59.999
For example, we could select the Stretch
distribution with backports,

99:59:59.999 --> 99:59:59.999
so we will get a 4.15 kernel with Stretch.

99:59:59.999 --> 99:59:59.999
There are some buttons we can say we want
to have some Debian developer tools.

99:59:59.999 --> 99:59:59.999
This is what I defined in the FAI
configuration, so just a list of packages.

99:59:59.999 --> 99:59:59.999
Here, you can enter you own packages.


99:59:59.999 --> 99:59:59.999
I will select the desktop.

99:59:59.999 --> 99:59:59.999
You can have an installation without any
desktop, so a very small installation.

99:59:59.999 --> 99:59:59.999
I will select the XFCE desktop, but all
the other desktops are here.

99:59:59.999 --> 99:59:59.999
The language, these are just task packages
that are…

99:59:59.999 --> 99:59:59.999
I think Debian has much more task packages,
I just searched which are

99:59:59.999 --> 99:59:59.999
the most common languages, and what I do
if I say I want the spanish language,

99:59:59.999 --> 99:59:59.999
also the keyboard layout is spanish.

99:59:59.999 --> 99:59:59.999
I know there are different combinations
and with local time,

99:59:59.999 --> 99:59:59.999
it's getting more difficult.

99:59:59.999 --> 99:59:59.999
This installation will install the clock
with UTC, so if you want to set

99:59:59.999 --> 99:59:59.999
your time, you have to do this manually.

99:59:59.999 --> 99:59:59.999
I want to cover the most common installations.

99:59:59.999 --> 99:59:59.999
We select english US, the desktop and,
as an example, the midnight commander

99:59:59.999 --> 99:59:59.999
and GIMP.

99:59:59.999 --> 99:59:59.999
I can add an email address so if it would
take longer,

99:59:59.999 --> 99:59:59.999
for example if this service will have
success and a lot of people are using it,

99:59:59.999 --> 99:59:59.999
you may wait for some minutes so your job
will be finished.

99:59:59.999 --> 99:59:59.999
So here are the comments, how to reconfigure
the keyboard or the timezone

99:59:59.999 --> 99:59:59.999
and then you just click "Create
the installation image".

99:59:59.999 --> 99:59:59.999
Now, in the background, there's some job,
a script, looking "Oh, there's a new job"

99:59:59.999 --> 99:59:59.999
and there's a summary of the configuration,
of the web configuration.

99:59:59.999 --> 99:59:59.999
Down here you see these are the
FAI classes,

99:59:59.999 --> 99:59:59.999
I will explain a little bit more about this.

99:59:59.999 --> 99:59:59.999
But with this information, FAI configuration
is generated,

99:59:59.999 --> 99:59:59.999
that's what normally the experienced
sysadmins have to create

99:59:59.999 --> 99:59:59.999
but here you just click on some buttons
and it will be done for you.

99:59:59.999 --> 99:59:59.999
In the meantime, we have some more
advanced features

99:59:59.999 --> 99:59:59.999
which I will also show you later.

99:59:59.999 --> 99:59:59.999
For example, this very simple installation
just creates one partition

99:59:59.999 --> 99:59:59.999
but you can also select that you want
to have a separate /home partition

99:59:59.999 --> 99:59:59.999
or using lvm just by selecting this
on the web interface.

99:59:59.999 --> 99:59:59.999
You can also add your SSH public key
for logging as root without a password

99:59:59.999 --> 99:59:59.999
or what's very nice, I found the new
Ubuntu installer does this,

99:59:59.999 --> 99:59:59.999
you can give your github account and
then there's a comment which

99:59:59.999 --> 99:59:59.999
receives the public key from your
github account and puts it

99:59:59.999 --> 99:59:59.999
into the root account so you can log in
without password.

99:59:59.999 --> 99:59:59.999
I think that's very neat.

99:59:59.999 --> 99:59:59.999
And if you have a repository with your own
packages, you could also add this and say

99:59:59.999 --> 99:59:59.999
"Please install those packages from
my publicly available repository."

99:59:59.999 --> 99:59:59.999
Let's see.

99:59:59.999 --> 99:59:59.999
As we see, this job finished in 74 seconds.

99:59:59.999 --> 99:59:59.999
Now, this customised installation image
is available for download.

99:59:59.999 --> 99:59:59.999
You can also download the log file.

99:59:59.999 --> 99:59:59.999
Since this is an installation image,
I first have to create

99:59:59.999 --> 99:59:59.999
a partial package mirror.

99:59:59.999 --> 99:59:59.999
This is done by the command 'fai-mirror'
and you can also read the log of

99:59:59.999 --> 99:59:59.999
this call of the fai-mirror, where a list
of all you packages with all the dependencies

99:59:59.999 --> 99:59:59.999
are available.

99:59:59.999 --> 99:59:59.999
So you see, these are the list of packages
and later they are downloaded

99:59:59.999 --> 99:59:59.999
and in the end, it says it created a mirror
of 1G of packages

99:59:59.999 --> 99:59:59.999
and since I have a local mirror,
it's very fast.

99:59:59.999 --> 99:59:59.999
This is the one part on the installation
image partial mirror with all the packages

99:59:59.999 --> 99:59:59.999
and the other is that the config space
which you can also download.

99:59:59.999 --> 99:59:59.999
So this is the config space that was
really created for you

99:59:59.999 --> 99:59:59.999
by clicking the web interface.

99:59:59.999 --> 99:59:59.999
If you want to do more things with FAI,
you can set up your own FAI server

99:59:59.999 --> 99:59:59.999
and use this configuration space.

99:59:59.999 --> 99:59:59.999
And, that's also very new, the two commands
that are used for creating this ISO image

99:59:59.999 --> 99:59:59.999
are now also listed there.

99:59:59.999 --> 99:59:59.999
First, create the partial mirror and then
create the installation image.

99:59:59.999 --> 99:59:59.999
Ok, copy link location…

99:59:59.999 --> 99:59:59.999
Let's see how good the network is here.

99:59:59.999 --> 99:59:59.999
[Q] It's a rather large image.

99:59:59.999 --> 99:59:59.999
Yeah, because it includes all the packages
