I also (think I) remember that, when booting from CD/DVD or floppy, the kernel creates a device node 'hd0root' to point to any hard disk root filesystem. Therefore to take a look around from CD booted maintenance mode you can:
Code:
# mount /dev/hd0root /mnt
# cd /mnt
# ls
Obviously to umount that you would:
Code:
# cd /
# umount /dev/hd0root (or # umount /mnt)
Without hd0root mounted (of course) you can:
Code:
# fsck -n /dev/hd0root
to see any damage to the hd root filesystem.
Hope that helps.

When I installed the SOLARIS 10 OS first time, the desktop would not start up, this was because of network setup. Reinstalled worked. After a week due to some problem I had to reinstall OS, installation went fine and but when i reboot I get this error.

umount
UMOUNT(8) BSD System Manager's Manual UMOUNT(8)NAME
umount -- unmount filesystems
SYNOPSIS
umount [-fv] special | node
umount -a | -A [-fv] [-h host] [-t type]
DESCRIPTION
The umount command calls the unmount(2) system call to remove a special device or the remote node (rhost:path) from the filesystem tree at
the point node. If either special or node are not provided, the appropriate information is taken from the list of filesystems provided by
getfsent(3).
The options are as follows:
-a All the filesystems described via getfsent(3) are unmounted.
-A All the currently mounted filesystems except the root are unmounted.
-f The filesystem is forcibly unmounted. Active special devices continue to work, but all other files return errors if further accesses
are attempted. The root filesystem cannot be forcibly unmounted.
-h host
Only filesystems mounted from the specified host will be unmounted. This option implies the -A option and, unless otherwise speci-
fied with the -t option, will only unmount NFS filesystems.
-t type
Is used to indicate the actions should only be taken on filesystems of the specified type. More than one type may be specified in a
comma separated list. The list of filesystem types can be prefixed with ``no'' to specify the filesystem types for which action
should not be taken. For example, the umount command:
umount -A -t nfs,hfs
umounts all currently-mounted filesystems of the type NFS and HFS. (The -a option only unmounts entries in the /etc/fstab list.)
-v Verbose, additional information is printed out as each filesystem is unmounted.
NOTES
Due to the complex and interwoven nature of Mac OS X, umount may fail often. It is recommended that diskutil(1) (as in, ``diskutil unmount
/mnt'') be used instead.

A umount command appeared in Version 6 AT&T UNIX.
