swap on a memory disk is a bit insane :)

swap doesn't need to be the size of the memory. That was true when
the swap space was used to back the whole virtual memory, nowadays
the swap is just extra memory and can be sized for whatever out-of-memory
conditions you need to survive.

The swap partition is also used for a crash dumps. So if you want to
analyze system crashes (and you do not have your own dump partition or disk),
it still can be handy to have a swap partition that is as large as
your memory.

True, on the other hand separate partitions help for recovery. E.g. if
/var is damaged you can still boot in single user mode. It also prevents
something like growing logfiles from filling up the whole disk, so
you can still use services that require space elsewhere.

I tend to use a single partition on systems that I can just throw away
and reinstall when damaged. But otherwise I use a few separate partitions,
in particular for / and /var (and /tmp is a memory filesystems, so it is
separate too).
