ISO9660 limits label length to 32 characters, this is enforced by
mkisofs.
Catalyst now truncates to 32 characters instead of failing when mkisofs
does, however the label formatting is inconsistent and loses some
information.
New label structure:
Gentoo ${ARCH} ${WHAT} ${STAMP}
Where 'WHAT' is skipped in some cases.
