I just compiled a complete new xsrc on a NetBSD/i386 1.3. The
resulting xterm showes a strange behaviour in adding new /var/run/utmp
entries: As a non root user it only adds entries, but never deletes
them. Compared with my old xterm the new xterm runs under the users
UID instead of root's, so that that might be the reason (Missing write
access on /var/run/utmp as normal user). But why has it changed!?
