Hello,
I partially take my words that I said in [1] back. aptitude sometimes needs a
bit more hints to give us what we really want, i.e. we need to feed it a custom
SolutionCost as default settings might not be sufficient for experimental,
backports and especially more complex buildd configurations.
Issues concern installation from non-default sources. You will find full
explanation in the patch header. Please keep commit message intact (if
possible) as it contains useful information on the "how aptitude resolver
works" topic.

Subject: [PATCH 2/2] AptitudeResolver: define a custom SolutionCost.
aptitude 0.6.2 release replaced resolver tiers with resolver costs. sbuild
AptitudeResolver used to rely on resolver tiers to deliver the following
behaviour:
1) Install non-default versions only if there is no solution among default (aka
candidate) package versions.
2) Solution should contain versions from sources with the highest possible
priority (when pulling from non-default versions).
While default SolutionCost (i.e. "safety, priority") configuration is supposed
to deliver this, it's apparently not enough. In particular:
1) "priority" cost component is broken in aptitude releases up to 0.6.3-3.2
(see #608786). It does not prioritize non-default versions by their
pin-priorities. However, thanks to Non-Default-Level safety level, the issue
does not affect configurations which have apt sources at two (one default and
one non-default) or fewer pin priorities. As a result, standard buildd
configurations (unstable, experimental, backports) are not affected by this
bug.
2) Once Non-Default safety level is breached, it is hard to guess what set of
non-default versions the solution will produce (it will be based on the "score"
criteria that is not easily predictable). Yet requirements are pretty clear: we
want as few non-default versions as possible. Fortunately, we can tell aptitude
that.
So sbuild custom SolutionCost achieves the following:
1) it gets the safest solution (tries only default versions first, then a mix of
default and non-default versions),
2) installs versions from the highest possible pin-priority source,
3) installs as few non-default versions as possible,
4) and finally picks a solution with the best score.
See /usr/share/doc/aptitude/html/en/ch02s03s04.html (aptitude-doc-en package)
for more information on aptitude resolver cost calculation.

Changes:
sbuild (0.60.9-1) unstable; urgency=low
.
* New release.
* sbuild:
- Don't automatically generate local archive signing key if
missing (Closes: #607945). If missing, abort build with an error
message and instructions for how to generate the key.
- Do not filter out environment variables starting with DEBIAN_ by
default (Closes: #608659). Thanks to Modestas Vainius.
- Do not filter out PATH environment variable (Closes: #610997).
Note this is not the user's PATH, but the $path in sbuild.conf.
- Aptitude resolver defines a custom SolutionCost in order to
improve resolver behaviour (Closes: #608789). Thanks to
Modestas Vainius.
- When running apt-get, use "-o APT::Install-Recommends=false"
rather than "--no-install-recommends" in order to support older
releases (Closes: #609811). Thanks to Marc Deslauriers.
- Purging the package removes generated files in /etc/sbuild/chroot
and /var/lib/sbuild (Closes: #608412).
- The architecture specified with --arch (defaulting to the host
system architecture) must match the chroot architecture
(Closes: #609151). This was previously allowed to be superceded
by the chroot architecture. This change is to avoid any abiguity
regarding the host/build architecture for the package being built.
- Add --no-arch-all option to force not building arch-all packages
(Closes: #613401). Thanks to Sebastian Harl for this patch.
* sbuild-createchroot:
- Use less restrictive permissions on chroot directory and schroot
configuration file (Closes: #608414). The chroot now has 0755
permissions, and the schroot configuration 0644.
- Don't require sudo access (Closes: #608429). The
Sbuild::ChrootPlain module used to run commands inside the newly-
created chroot was using sudo to run commands when already
running as root. sudo is no longer used when root.
- Remove use statement which prevented command-line options being
registered (Closes: #610007, #607606). Command-line options now
work correctly.
* sbuild.conf:
- $environment filter is syntactically correct (Closes: #610997).
Thanks to Jakub Wilk.
- $apt_allow_unauthenticated is documented to use apt-secure(8)
(Closes: #608971).
* sbuild.1:
- Document the temporary local archive used by the apt and aptitude
build dependency resolvers to store and install dummy dependency
packages (Closes: #608972).
