Hello, I have a Debian sid system where there is a problem with the unmonting of the /var filesystem that causes a delay in the shutdown process:

First, how can I debug what is going on, namely how can I see which process is keeping /var busy? Second, where does the 90 seconds timeout come from? Does it make sense to wait for a timeout if the un-mounting of a partition fails a shutdown? Thank you!
