Oh indeed, it is not as easy as I thought it would be - neeed to hack
on sysinst again and make this better.

There is no easy way in sysinst to do a /tmp partition with tmpfs right now,
you need to work around this by:

 - at the "choose partition sizes" stage

    1) set /tmp to size 0
    2) add a user defined partition for mountpoint /tmp2 and give it the
       size you want

 - at the next "partition details" stage (you will notice /tmp vanished,
   corrctly for a tmpfs thing, but /tmp2 is still there)

    1) edit the /tmp2 entry and fix the mount point to /tmp, and select
       whatever file system you want to use


You can't add the correct partition at the first stage because even with
size 0 and tmpfs magic it won't allow you specifying /tmp again for another
partition. This obviously is a bug.
