Comment 2 for bug 248932

The reconfiguration was indeed not successful, as I just found out while trying to revert on the working copy I had tried to reconfigure before. This can be reproduced as follows:

$ bzr init-repo --rich-root-pack repo
$ cd repo
$ bzr init branch
$ cd branch
$ echo foo > file
$ bzr add
$ bzr ci -m r1
$ bzr reconfigure --standalone
(errors as described above)
$ echo bar > file
$ bzr revert
bzr: ERROR: bzrlib.errors.NoSuchRevision: KnitPackRepository('file://.../repo/branch/.bzr/repository/') has no revision ('...',)

I consider the problem quite serious, as it can severely damage a branch. Unless you have backups around, this could cause serious trouble. Thus I suggest an increase to the importance of this issue.
