SUMMARY: Help: "boot -s" not working after getting "Error opening PAM libraries"

I changed root's home directory to something not on the / partition and now I
can't log in.

Here is the steps to change things back:
1. Put the Sol 8 boot disk in your cdrom;
2. stop-A, boot cdrom -s;
3. mount root drive to /a; 
4. edit /a/etc/passwd to change root's directory to /;
5. reboot.
