[Sunhelp] Relocating partitions

[Kevin Stevens]

I need to swap out a disk drive, and hence relocate the partitions/mount points
on it temporarily.  For example, /var/mail is currently on this device, I want
to relocate it to the system drive which has space free within /var, but no free
partitions.  Several days later I'll want to move it back to the replacement
drive.

It looks like this can be done with some combination of cp, ln, and swearing;
but also seems as though it happens often enough that there might be a recipe.
Can someone point me at a FAQ or howto?

Tangentially, where and how are Solaris 8 partitions managed, anyway?  I get
lost when I can't find an fstab.  ;)
