2005/05/24 restrict_chown, rstchown (restricting users from changing ownership)
Way back when, chown could be run by everyone. Berkeley Unix
saw that as a bad idea and made it root only. Nowadays POSIX
says it's up to you.
The default for Unix systems is that users can't change the ownership
of files. That's probably the way it should be left, as the ability
to do so opens up very bad security issues. Nevertheless, some systems
allow this. It may be from a setting in /etc/system:
Or, it may be "sysctl" that controls this:
sysctl -a | grep chown
fs.xfs.restrict_chown = 1
For these, a setting of 0 would allow non-root users to use chown.
On other systems, this sort of thing is a "privilege": HP-UX
lets you control this (and other things) at the group level. Of course
this can be allowed through sudo or
similar privilege escalation
