Boot from CD or installation floppy and select 'fixit' from the main menu. If you don't have the CD-ROM, you'll need a copy of the fixit floppy as well. Then do the following: # mknod /dev/ad0s2a c 116 0x00030000 # fsck -y /dev/ad0s2a # mount /dev/ad0s2a /mnt # mknod /mnt/dev/ad0s2a c 116 0x00030000 After that, you should be able to reboot with no problems.
