[Bug 1552539] Re: Ubiquity Erase Disk and Install Fails to create Swap Space

[Martin Pitt]

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.
