Hello all,
Just wondering what the effect would be on removing the set u/g of
the following files. Most of these are -s kmem or tty or dialer.
First of all what difference would the kmem ones have on the root users use
of these files, I presume nothing but I wouldn't mind being certain.
I suppose the real question is does anything fall over if the kem /tty
groups are changed on systems with only the root user.
/bin/ps
/sbin/dmesg
/sbin/dump - why is this tty ? -r-sr-sr-x 1 root tty 188416 Jul 17 03:23
