Many years ago I checked and chmod only changed the MTIME of a file if
it needed to make a change to the permissions, now the mtime is changed
on every file (even if no change is needed).
The -c option works as expected (only tells you if a change was needed
to meet your command.
So is this a bug, or was it changed for a spcific reason ?
Is there a command line option to stop it from doing this?
Has this already been fixed (and I just need to update - version info
below).
The chmod distributed with FreeBSD still works as I would expect.
Note - we found this behaviour changed when trying to figure out why our
incremental backups are so large (it may have been changed for many years).
Thanks.
