Now, that was interesting.
Unplug the ATA controller and the CD-ROM is bootable-from. With a bootable CD-ROM, we can (temporarily) get a network module up and with a network module, we can by sheer force of apt get a new kernel down and with a new kernel, we can then shove the ATA controller back in place, creating vastly more diskspace than before (imagine a decimal order of magnitude), making for lots of nicely chunky free space.
Then, of course, comes the fun of juggling data around and coalese stuff into less unsuitable chunking. Should've gone for LVM, shouldn't I?
Anyway, that means all bar lists should be back on-line and I should hopefully have time to sort them through this week.
