Your package udisks appears to include a file in /var/run or /var/lock. With an upcoming change in Rawhide these directories will now be mounted as tmpfs. For details about this change please consult http://lists.fedoraproject.org/pipermail/devel-announce/2010-November/000726.html For your package this means that you need add %ghost to all files that are placed in either of these two directories. Please make sure to make this change in time for the F15 cycle. For details about %ghost see http://www.rpm.org/max-rpm-snapshot/s1-rpm-inside-files-list-directives.html#S3-RPM-INSIDE-FLIST-GHOST-DIRECTIVE , for more information on the F15 feature see the feature page https://fedoraproject.org/wiki/Features/var-run-tmpfs . If your package already uses %ghost on these files, feel free to close this bug report right-away. Sorry for this mass bug filing, and if you have any further questions, don't hesitate to ask on fedora-devel or ask me personally. Thank you, Lennart
that Matthias committed was wrong and caused udisks to actually not work at all when /run is a tmpfs (udisks really needs its /var/run/udisks directory and won't mkdir it itself if it's not thtere, for better or worse). I've committed a better fix
that actually works (see bug 733161).
I just fixed udisks upstream to create its /run directory on demand. This will be in udisks 1.0.4 so I can remove the /etc/tmpfiles.d hack.
