[buildd-tools-devel] Bug#619332: feature regression in 0.62.0: no way to keep session only if build fails

[Modestas Vainius]

Package: sbuild
Version: 0.62.0-1
Severity: normal

Hello,

you added --keep-session:

      + A new option, --keep-session, has been added (Closes: #609658).
        This prevents the automatic removal of session-managed snapshot
        chroots.  Previously, snapshots would not be deleted if purging
        of the build directory or build dependencies was disabled, but
        this was not always desirable, hence it is now configurable
        separately

While I agree with general idea that end_session should be configurable 
individually, you actually removed the feature to keep the session only if 
build fails. Obviously I have no way of knowing if build is going to fail in 
advance so --keep-session as boolean command line option is mostly useless for 
me.

Please allow to set --keep-session via both command line and sbuildrc with the 
same set of values and behaviour that $purge_build_* options accept.
