Hmm, I may have inadvertently broken this in
http://anonscm.debian.org/gitweb/?p=buildd-tools/schroot.git;a=commitdiff;h=51ccba7088f665e0e463778c09230fc44a38106a
when fixing #675189.
The idea was that if you use profile=foo, then setup.fstab=foo/fstab,
and SETUP_FSTAB=/etc/schroot/foo/fstab.
When you set script-config=foo/config, it was setting profile=foo
for foward compatibility, but /not/ setting setup.fstab etc. The
above change messes that up.
However... by setting profile=, it would end up in the session state,
which would result in it being set in any case, so it would only
"work" during session setup. What we probably need to do here is
- not serialise profile= if script-config is in use
- not create the extra settings when set_profile is called and
script-config is set. This has downsides though; it prevents
profile= from overriding script-config=.
Given that the foo/config files are removed for all the stock
profiles, we most likely want to set setup.fstab in all cases where
foo/config does not exist. I'll have to give this some more
detailed thought to make sure I've got all the different use cases
covered.
BTW, please also see
/usr/share/schroot/setup/common-config
which also does some initialisation of these variables if not
already set. It should source the config file (if present),
and then set up the paths correctly.
Regards,
Roger
