file ownerships changed

[Rik Herrin]

I'm afraid not.  However, in the future, you could
prevent this from happening again by doing something
like running a CRON job every day to backup the
permissions on all files on your system.  For example,
a quick hack would be something like

01 1 * * * /usr/bin/find / -exec getfacl {} \; >
/tmp/backuppermissions.txt

which would save the permssions of all directories and
files into /tmp/backuppermissions.  Having a look at
the resulting file would give you entries such as:

# file: bin
# owner: root
# group: root
user::rwx
group::r-x
other::r-x

# file: bin
# owner: root
# group: root
user::rwx
group::r-x
other::r-x

...

It shouldn't be too difficult to write a quick Perl or
bash script to process this file (and the directory or
files that you are interested in) to restore them to
their previous permissions.  Of course, now is too
late, but it's something to think of in the future.
