Bug Description
Binary package hint: ureadahead
On several of my systems (including Lucid, Maverick, and Natty), I find that /var/lib/
In looking at the ureadahead source, it seems like it intends to unmount it when it is finished, so this is a bug. In looking at the upstart configurations, it seems that ureadahead is started multiple times, once for every mount point. It didn't look like the tracing code supported multiple instances running at the same time, though. Perhaps they are racing each other?

Ah, no, something else is going on. This is a left over in /etc/mtab. /proc/mounts does not show it:
$ mount | grep debug
none on /sys/kernel/debug type debugfs (rw)
none on /var/lib/
$ grep debug /proc/mounts
none /sys/kernel/debug debugfs rw,relatime 0 0
