So far, it's been up a half hour or so, and it's still ok. I used
'linux single init=/bin/bash', btw. If the problem were time-dependent,
it would've hung within 5 minutes of booting. So the problem is fs
corruption, I think. Does that sound about right?
Then the hardware is probaby okay, and you've just got some file
corruption or something similar. The "linux -b" option at the lilo
prompt should allow you to then start running the startup scripts
manually to find out which ones are causing you grief.
Phew, ok. As I'm booted now, can I manually get to runlevel 3 and run
the scripts? I had to manually run the /etc/rcS.d scripts, but I'm not
sure about changing runlevels. Is there anything special about
runlevels that I can't tweak manually? Or do I just change runlevels by
running the scripts for the runlevel and it'll take care of itself? I'm
pretty sure that if I switch runlevels the *normal* way (through
telinit/init), I can't run the scripts manually. Right?
