I actually didn't run into the problem in sysinst - I ran into it
building -current userland. It was very difficult for me to figure out
what was filling up as well because when I ran df, it would show only
95% usage of /. However, when I followed the workaround of symlinking
/tmp (and /var) to a directory on a larger partition, / stays around 85%
and -current userland builds. That's why I made the connection that / is
being made too small in sysinst as indicated by the PR.

I haven't been following up on your earlier email to me about this
because I haven't gathered enough information that I felt would be
useful. Is the focus of a solution figuring out sysinst's problem or
making / bigger? If it's the latter, my thoughts were that this might be
a good opportunity to offer partition themes.
