[olug] How to force internal HDD to be sda?

[Kevin]

I'm going to take a wild guess and say that this is just an
intermediate step in what you're trying to solve. If what you want is
really to just put an entry in your fstab file, then an alternative is
to check out the various options under /dev/disk(I'm using RHEL
5.1/CentOS 5.3). Various options are
 * by-id
 * by-label
 * by-path
 * by-uuid

At least one of those should remain consistent across reboots,
regardless of the boot media.

On my laptop (mostly), in Fedora 13 if I boot with the external drive plugged in via USB it gets assigned /dev/sda and the laptop internal drive gets assigned /dev/sdb.  When the external is not attached the internal gets assigned /dev/sda.  Why?  Sorry to be blunt, but that is just damn stupid.  (Says the crusty old UNIX guy)
