Recently I saw a bug report about dpkg not being able to replace a file
because program was being executed at the time of installation ("cannot
overwrite text file" was the message, IIRC)... is this still an issue?
If not, perhaps the section 7.2 "Debian claims to be able to update a
running program; how is this accomplished?" in the Debian FAQ[1] needs to
be adjusted.

or at any other closer mirror. :)
