Thanks for proposing this.  schroot (1.0) is currently frozen for
etch, but changes can go into the trunk.

I would very much like to allow easier customisation of the setup and
session scripts, but I would also like to keep the configuration file
as clean and simple as possible: I don't want to add a new
configuration option for every tweakable aspect of the scripts,
because I'd like to keep it /user/ extensible.  There are quite a
number of other things that people want to customise, so I'd prefer to
take a more general approach here.

An alternative approach I've been considering is to source a shell
script at the start of each setup script which would simply set a few
shell variables in the form

FOO="bar"

which could then be used by any of the scripts.  The configuration to
use could then be specified by a single configuration file option,
such as

  setup-script-config=/etc/schroot/custom-config

This could be unique to one chroot, or could be shared by different
chroots.  As it would be a shell script, it can be easily adapted by
users who want to allow customisation of their own setup scripts.

Does this sound OK?


Regards,
Roger
