This is the only modified file, so far, from the original distribution; because Tomsrtbt runs completely off a 1.7M floppy, it has to go through some conniptions to decompress the filesystem. I comment out the uncompress lines. The last three lines: gzip -d /usr/doc/*.gz . /usr/doc/rc.custom #umount /fl OK, so rc.M finishes and control transfers back to init. Here's the entire inittab: id:4:initdefault: si:S:sysinit:/etc/rc.S rc:5:wait:/etc/rc.M ca::ctrlaltdel:/bin/shutdown -t5 -rfn now "CtlAltDel" l0:0:wait:/etc/rc.0 l6:6:wait:/etc/rc.6 c1:5:respawn:/usr/bin/agetty 38400 tty1 c2:5:respawn:/usr/bin/agetty 38400 tty2 c3:5:respawn:/usr/bin/agetty 38400 tty3 c4:5:respawn:/usr/bin/agetty 38400 tty4 Is agetty the problem? AHA! Change the last 4 lines to: c1:5:respawn:/usr/bin/agetty 38400 console #c2:5:respawn:/usr/bin/agetty 38400 tty2 #c3:5:respawn:/usr/bin/agetty 38400 tty3 #c4:5:respawn:/usr/bin/agetty 38400 tty4 and we get: /usr/doc/*.gz: No such file or directory .: Can't open /usr/doc/rc.custom (none) login: root /bin/login: cannot open /etc/passwd: no such file LOGIN FAILED OK, so uml doesn't like tty1-4?

The only changes I've made from the file I mailed you are the passwd file: root::0:0:root:/root:/bin/ash guest::500:500:guest:/tmp:/bin/ash and the 4 line change at the end of inittab I listed above.
