When maintaining of pty's is done by /dev/pts or pt_chown,
there it NO reasin, IMHO, to make a program setuid-root to maintain
utmp. It's enough to
addgroup utmp
chgrp utmp /var/run/utmp /var/log/wtmp
chmod 664 /var/run/utmp /var/log/wtmp
chgrp utmp a_program
chmod 2755 a_program
I live with a patched for Unix98 pty stuff glibc2.0 and such
configuration for a few months and have things ok. Are there
any potential problems in such a configuration?
