Bug#874188: fai-client: Integrate some form of file templating system

[Riku Voipio]

Hi,

I've used envsubst[1] in my fai setup. envsubst comes from gettext-base
so most people have installed and it's very easy to use. jinja2 is more 
powerful (can do loops etc), so there are some cases where it is more
useful.

hi Thomas - 

as it is python-centric it may not be the best choice for fai, but
given ansible's increasing popularity i would suggest jinja2 is worth a
look.

thank you!

Any suggestions, which template system to use? Or which features this
template system should support?

Here are some features I know:
- variable substitution
- loops
- execute any sort of code

IMO variable substitution is the most important one. What's your oppinion?

[Noah Meyerhans]

Package: fai-client
Severity: wishlist

In our use of FAI for generating the stretch cloud images, we use fcopy's
preinst scripts to implement a crude form of templating. See
https://anonscm.debian.org/cgit/cloud/fai-cloud-images.git/tree/files/etc/apt/sources.list
for the files and script.

In order to avoid having to re-implement the templating system everywhere
and encourage reduced repetition throughout the config tree, it would be
really helpful to have some kind of file templating system integrated into
FAI, possibly in the fcopy program directly.

Thanks
