[buildd-tools-devel] Bug#681884: How to discover which process own the mount-point

[Franco Martelli]

schroot works fine, no problem whether daily used. The misbehavior
reported happens when the system is *resumed* from suspend-to-ram (not
hibernate: suspend-to-disk) after a day.
schroot has trouble when closing session because of the schroot's
mount-point is reported busy:

4099rce  4116rce  4140rce  4143rce

The mount-point is an empty directory, the lsof utility returns no
output and sadly fuser's output doesn't help me therefore as workaround
I've to reboot and remove schroot's session files by hand.
I'd be happy to avoid rebooting each time. Any idea?
TIA
