FTWCA storing config/ in VCS, reloaded

[Daniel Baumann <daniel@debian.org>]

Hi,

and this time it's even working :)

Let's repeat...

If you are using a version control system to store your live-helper
config directory, you should not store the generated files config/* in
it, but only save which arguments you passed to lh_config and your own
files that you put into the config/*/* directories.

If you would store them in the vcs, you would have troubles over time,
as the format of the generated config files may change. If you use the
(almost) stable interface to generate the config, the lh_config tool,
you can avoid that completely and always have a working and up2date
config without manually updating/touching it.

In order to ease this, lh_config from ive-helper in git (which gets
uploaded to unstable this weekend) does check for a scripts/config.sh
file. If present, it executes it instead. Same applies to
scripts/clean.sh for lh_clean.

...and the workflow would be:

1. create a git repository

2. add a .gitignore file, example at
http://git.debian.org/?p=debian-live/config-daniel.git;a=blob;f=.gitignore;

3. add a scripts/config.sh with your complex lh_config call/options,
example at
http://git.debian.org/?p=debian-live/config-daniel.git;a=blob;f=scripts/config.sh;

4. commit that

5. when you actually build your live system, you checkout your
repository in your build directory

6. run lh_config (any additional argument is optional and will be
appended to the lh_config call in scripts/config.sh).

7. lh_build

I think this is almost sane. Cluebats, as usual, are welcome.

Regards,
Daniel
