Subject: Re: boot process hangs on init of mysqld
Thanks Keith! Unfortunately, this machine uses Lilo instead of Grub.
Can something similar be done to enter 'single user mode' when booting
I don't have a machine with LILO on it to test with, but, try the word "single" at the LILO: prompt, e.g.
Press RETURN. This should bring it to single user mode, no guarantees, since I can't test.
