Actually, this is what the installer does, are or least is supposed to
do. Kevin Price ran into this problem too recently and I'm not sure
how to interpret his finding. Maybe someone more familiar with
partman (or the kernel?) can comment.
Here is what Kevin found:

|
| That surprises me. On a closer look into the log, you're right.
|
| From a user's POV, the first mkfs-ext3 attempt failed, but just starting
| it again worked out ok.
|
| Now from looking into the log, it looks strange: It adds swap, then
| attempts to format ext3, then comes OOM and kills mkfs.ext3. Then comes
| the interesting part: It seems to add swap again. That time mkfs.ext3
| runs OK. So maybe the first time adding swap, the swap gets disbled
| immediately after, triggering OOM?
|
| See the attached log excerpt.
