is it ok to change owner group /dev/tty[0..7]
to tty group?

thank you

[eugene@beautifulmind project1]$ write charles tty/7
write: you have write permission turned off.
[eugene@beautifulmind project1]$ mesg y
mesg: error: tty device is not owned by group `tty'
[eugene@beautifulmind project1]$ ls -l /dev/tty* | grep 'root root'
crw-rw-rw- 1 root root 5, 0 Feb 23 2002 /dev/tty
crw--w---- 1 root root 4, 0 Feb 23 2002 /dev/tty0
crw------- 1 root root 4, 1 Sep 12 08:22 /dev/tty1

How can you write to charles in tty7 ? he is not at all logged in tty7 Otherwise the owner of /dev/tty7 shud be charles.

also i think the problem can be solved by changing the group of all /dev/tty* from root to tty
