Subject: please provide packaged schroot instances, ready to use

Date: Mon, 06 Jul 2009 10:26:10 +0200

Package: schroot
Version: 1.2.3-1
Severity: wishlist

[ Reporting this feature request / design document as requested in the
  discussion started at
  http://lists.debian.org/debian-devel/2009/07/msg00135.html ]

In essence: we want packages that can be installed to provide ready to
use schroot instances.

Two use cases has emerged during the discussion:

1) schroot instances used by developers, e.g. integrated with pbuilder
   / cowbuilder to build packages for various Debian(/Ubuntu?)
   suites. That can result in packages like
   schroot-instance-{sid,squeeze,lenny,...} with Provides matching
   schroot-instance-{stable,testing,unstable}. (The "instance-"
   sub-string is an addition of my own, not sure it is nice though :))

2) "poor's men multi-arch", i.e., the ability to have 32 bits chroots
   on true 64 bits systems to install and run 32 bits missing 64 bits
   equivalents

Various design points have been already discussed:

* chroots can be debootstrap-ed at postinst

* APT settings can be inherited (in some smart way though, because
  they cannot simply be copied) from the host system

* chroots' conf can be simply dropped into /etc/schroot/chroot.d/

* mechanisms to update/upgrade in a batch way all schroot-instance's
  should be developed. sbuild wrapper scripts to do that can be
  mimicked. For security upgrades, unattended-upgrades integration
  should be investigated

* wrappers to run apps from a given chroot should be developed, most
  importantly for the multi-arch scenario. Something a-la wine could
  do, but it needs to be easy and most likely able to be used as a
  launched in desktop environment

... did I forget something?

Cheers.
