Description of problem:
The file /etc/fstab contain the line:
This implies that the apparently mounted partition is not the real
mounted partition. The root file system will also not be checked
while the system is booting.
On my system RH 7.3 was installed on hda2, the complete system
was copied to a partition on a new drive (hdd, hdc is a cdrom).
df / show "/dev/hdda2 ..." instead of "/dev/hdd7 ..." The size
reported correspond to the correct partition.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. install RH
2. create a partition on an other drive and copy the content of the
actual system to the new partition, edit the file /boot/grub/menu.lst
in order to be able to boot the new "installation"
3. reboot the system with / at the new partition.
Actual Results: see description,
Expected Results: correct information about the real mounted file system
The idea of using LABEL=/ within /etc/fstab is good but the boot
process work not correctly.
Modifying the lile "LABEL=/ ..." with e.g. /dev/hdd7 / ..." solve the
problem but is not as pretty as the original line.
If you copy and are using a new root fs, then you need to update the label on
the destination partition as well. The label is set in the filesystem
superblock, it's not really very deep magic.
