I'm having trouble tracking down the exact details, since I didn't
change the script immediately after the report. I found a comment from
me to mdz in #ubuntu-devel on 2006-08-02, saying:
"apparently powerpc had problems burning for some people even in
dapper; it was below what I understood the real size limit to be, but
above 700MB, and I've had reports of some software/media (unsure
which) not liking that"
I believe LaMont may have been one of those with problems?
Lathiat made a second-hand report of problems with that 702MB image in
#ubuntu-devel on 2006-06-06, with nautilus-cd-burner on breezy (though
it could easily be the drive firmware or the media at fault).
TBH, since problems like this have apparently entirely gone away with
the lower limit, I'm inclined to be extremely cautious.
