My machine hangs during the boot process. It seems related to ps.

My machine hangs during the boot process. It seems related to ps.



When the system boots, the first invocation of ps will try to
recreate /tmp/ps_data. To this end ps scans the /dev tree.
Under some circumstances, a loop exists in /dev and ps will
run forever. Most of the time this loop is caused by the symbolic
link /dev/bd.off. While this link usually points to /dev/term/b,
it sometimes get truncated and points to /dev instead.



Fix: rm -f /dev/bd.off; ln -s /dev/term/b /dev/bd.off


Use truss(1) to determine whether this is really the cause of your
problem.
