Description Jeremy Olexa (darkside) (RETIRED) archtester gentoo-dev Security 2010-11-15 15:54:39 UTC 
With FEATURES=-collision-protect, it tries to remove detected collisions on / instead of $EPREFIX/ - results in traceback and no workaround (that I can think of besides manually rm'ing the files)

Logs attached.

scared to try

[prefix 8faf55a] _unmerge_pkgfiles: improve out-of-prefix unmerging check

Bug #345633 is likely caused by a corrupted/invalid CONTENTS entry (from
previous buggy Portage releases).  It shows, however, that the unmerge
code wasn't protected well enough against "unmerging" files outside of
the Prefix.  All entries are evaluated now to see if they are within the
Prefix and a warning is issued when they are not, preventing any further
actions to be taken.
Comment 7 Fabian Groffen gentoo-dev 2010-11-30 19:44:35 UTC 
--- !prefix path/to/file

warnings added in 2.2.01.17304

no longer attempts to unmerge files outside of the prefix.
Comment 8 Jeremy Olexa (darkside) (RETIRED) archtester gentoo-dev Security 2010-12-01 18:32:58 UTC 
warnings work since the CONTENTS files got so messed up.

FEATURES=-collision-protect is the workaround.
