Bug#112853: apt: can't always remount /usr read-only after running apt-get

[<chr.ohm@gmx.net>]

Package: apt
Version: 0.5.4
Severity: normal

hi.

i usually have /usr mounted read-only and just change it to install or
dist-upgrade. but sometimes after running apt-get dist-upgrade/install when
i try to remount /usr read-only, it says:
mount: /usr is busy

so it seems apt-get opens some files on /usr as read-write.

bye
