section
This link was broken, but also points (if it was fixed) to the head of
the current section so it's not useful. Remove the sentence entirely.

We were not consistent in our headings inside this section, with some
operating system notes using:

and others using:
=head2 Windows
=head3 System disk on a Dynamic Disk is not supported

Subject: [PATCH] docs: Add more description for --memsize option
The adjustable --memsize option, which increases the amount of memory
available in the appliance, is necessary to work around at least one
unfixable setfiles / glibc bug. Document in more detail what this
option does in a new section, and mention this issue. (As the issue
can't be fixed properly, this is a documentation-only fix).
