Comment 8 for bug 9459

Happened to me twice while setting aside close to minimum disk space for an
install of breezy Colony 4 and preview (2G)
I assumed the minimum is still 1.8 G as I did not find updated requirements for
breezy.Is estimation of the total disk usage hard?
I naively assume sum of deb sizes packed and unpacked, once the set of packages
is known.
I know windows refuses to start installation unless a certain amount of space is
free.
