Yes. You must look at /etc/fstab on the system that's being booted.
This may require booting off the CD in rescue mode if the /etc/fstab
uses drive identifiers for filesystems that are necessary for booting
(e.g. /, /boot and /usr) and those identifiers no longer match the
partitions.
In other words, if the /etc/fstab says something like:
/dev/hda1 /boot (blah, blah)
/dev/hda2 / (blah, blah)
/dev/hda7 /usr (blah, blah)
/dev/hda5 /var (blah, blah)
and you swapped hda7 to hda5, then the system won't be able to mount
/usr correctly (it'll mount /var as /usr) and stuff will break big time.
Now, if fstab use labels instead, such as:
LABEL=/usr /usr (blah, blah)
this isn't a problem, as the system will look for a partition that's
labeled "/usr", regardless of where it is. This is the ONLY time that
I think labels are OK. Generally, I avoid them like the plague.
