According to Gary Jennejohn: > There are many more pseudo-ttys in /etc/ttys now. AFAIK utmp allocates > an entry for every one of them at startup. utmp concepts are ancient. It is indexed by the tty/pty number so can grow rather large but it should be a sparse one too. I remember talks about replacing it with something a bit more modern. Backward compatibility is assured through login(3) although it would break programs digging in the utmp file itself. SVR4 had utmp/utmpx and setutline/getutline BTW... cf. sessreg(1) System V has a better interface to utmp than BSD; it dynamically allo- cates entries in the file, instead of writing them at fixed positions indexed by position in /etc/ttys. -- Ollivier ROBERT -=- FreeBSD: The Power to Serve! -=- roberto_at_keltia.freenix.fr Darwin sidhe.keltia.net Version 9.2.0: Tue Feb 5 16:13:22 PST 2008; i386Received on Wed Aug 27 2008 - 09:46:26 UTC
