I would like to try the readonly-medium variant. That give us a lot of
room to include support for graphical installations, exotic targets (MD
rootfs, loop mounted fs, ...) and so on. It also plays nice with
different source media (CD-ROM, NFS mounted partition, SMB, or even
that HTTP-fs thingie I saw a few months ago... I wish I could remember
the URL...).
