I'd prefer that we fix this by moving to swap files. Doing so will offer no
additional space, but will more clearly line up with the user's expectations
of the size of the partition.

I don't think this is the same problem. Ubiquity has logic in it to check
that the requested partition size is greater than a multiple of the size of
the read-only copy of the squashfs. This is the figure that's presented on
the "Prepare to install Ubuntu" page.

debian-installer, lacks the ability to have similar functionality due to its
flexibility and construction. It is close to impossible to determine the
minimum size needed for the installation in this environment. If you resize a
partition too small and try to install onto it, then sorry, but don't do that.

This should not happen if you choose the "Upgrade/Reinstall Ubuntu" or "Erase
Ubuntu and reinstall" options in ubiquity. These options are made to reuse
the existing swap partition. Please file a separate bug if this not the case.
