From: Richard Tollerton <rich.toller...@ni.com> If $DEVCACHE_CURRENT_SYSCONF gets stored in the cache tarball, and extracted, then udev-cache will needlessly rebuild the cache on every future boot. The direct fix to this is to explicitly exclude it.
Investigating this also uncovered that we're also archiving everything under other filesystems, including /dev/cgroup, /dev/shm, etc. This shouldn't be happening. The fix is to use `tar --one-file-system`, but this is GNU-specific.
