I have a half-baked idea that I will throw out there to see if anyone
picks it up....
Would it be possible to have a standard Linux file system flag
(at least for ext2 and ext3, maybe reiser would pick it up too?)
that would indicate if a file had been installed via a package and
never modified. Call the flag the "nobackup" flag?
For example, when "rpm" or "apt" or "yast" was installing a file
it would set this file system flag, and the VFS layer would always
unset this file if it was modifying anything other than the atime
of the file?
This way finding modified package owned files, or non-package owned
files would be very simple for backup software, or rsync jobs.
Also, one could run a script to mark files prior to backup runtime,
something like "find / -type f -name "*.dbf" -exec chattr +notape {}\;"
