Comment 22 for bug 1552539

Dave has a way to reproduce this in a loop on his system. I logged in through ssh and attached strace -fvvs1024 to all the running processes with "ubiquity" or "partman" in the name. Attaching the raw data, I'll stare at it in a bit.

I think the next step is to find out which precise commands ubiquity and/or partman are running in order to set up the swap partition, and then try to reproduce these on the command line to study what's up with those. I don't see any commands logged in the partman log, hence I was trying strace.

Sorry, I know absolutely nothing about partman or the partitioning/fs creation part of installer at large, so I'm just poking in the dark so far.
