Hi!
I've updated Fai to 5.0.1 and rewrote my config space. For most setups,
I use setup-storage now instead of custom scripts.
I use Fai to install the notebooks for our linux and open-source
trainings. My goal is that the resulting installation looks as similar
as possible to what the installer of the distribution (eg. CentOS,
Debian, Fedora, openSuSE, SLES, Ubuntu) would produce.
SuSE has been using btrfs since some time. Unfortunately, the BTRFS
support of setup-storage is not useful for that purpose. So I had to
write my own script.
If you hit a similar challenge, you may have a look at my solution in
the attached script.
