The problem with that is that unless you edit fstab before the initial
reboot, (difficult to do) to remove the auto-found swap partition on
sdb, it will be found and mounted. But by then it likely has been
I think my point is that its a shrug, or should be.
If you want separate swaps because you are dual booting, that isolation
can be handled by a root edit session on /etc/fstab of each install.
And it may sound counterintuitive, but if the install on sda uses /swap
on /sdb, and the install on sdb used the swap on sda, the machine may be
noticeably faster when its actually useing swap. OTOH. I have never
done it. I just think its possible with no side effects other than a bit
faster when its using swap when booted to either install.
Unless your machines are really memory starved, swap s/b clean anyway if
its not been booted long. I'd also expect that doing, as root,
swapoff -aRETURN should result in a clean swap being found at the reboot
you are using to install. Then it wouldn't matter if it was
reformatted. I have never believed in having anything in swap actually
surviving a reboot anyway. At 12 days & change uptime, I show 58 megs of
swap in use. So this 3.16.0 kernel I'm running now is not particularly
swappy, but it also recognizes the 8Gb of dram in this machine.
OTOH, each machine seems to have a mind of its own. So my advice may be
Linux it seems to me is entirely too eager to outwit the experienced
user. But my oar is too small to fit the oarlocks in this ship called
linux. Linus may have had a very good reason for making it do what it
