Re: SOS!Help Me pls!!!
try booting from a OS core cd or a make_recovery tape if you have one.
If you don't it involves a bit of hacking around let me know,

- Insert CD
- Reboot your system
- stop the boot sequence
- search for your CD device :
- search IPL (this will all bootable device)
- boot Pxx
- Answer NO for Interact whith IPL
- In the menu select "Run a Recovery Shell"
- Then x Exit to shell
- chroot_lvmdisk
- cd /ROOT
- chroot /ROOT /sbin/sh
- vgchange -a y /dev/vg00
- mount -a
- now you can rename your directory
- reboot normally
Good Luck !
Patrice.

Re: SOS!Help Me pls!!!
Pls note...never ever change the shell of root from /sbin/sh to anything else.
Pl do man passwd: The login shell for the root user (uid 0)
must be /sbin/sh. Other shells such as sh, ksh, and csh are all located under
the /usr directory which may not be mounted during earlier stages of the bootup
process. Changing the login shell of the root user to a value other than /sbin/sh may result in a non-functional system.
================
The root account must use /sbin/sh, and may not be
changed to any of the shells in /bin. There are a couple of reasons for this,
all of which involve /usr not being mounted in single user mode.
When the system boots, one of the first things it must
do is exec a root shell at single user mode to run fsck and the various rc
scripts. At this time, the only file systems that are mounted are
/ and /stand. /bin is really a symbolic link to /usr/bin, which is not mounted, so the shells there are not available until /usr has been fsck'd and mounted, so we have no way to exec one of them. In addition, the files under /usr/bin are dynamically linked,
meaning the shared libraries under /usr and the dynamic linker /usr/lib/dld.sl must be available to load them (/lib is also a symbolic link to/usr/lib). The executables in /sbin are statically linked and do not require the shared libraries or the dynamic linker.The shell under /sbin/sh is not the old Bourne shell - it is a statically linked version of the posix shell, which should have most, if not all,of the functionality of the Korn shell.
Pls revert in case of any problem...
