It is probably worth getting 2.0.85, I have recompiled ash, updated luasocket, removed lua regex and crypt, rewritted busybox init to make it allow adding init entries on HUP, modified the bz2bzImage progress indicators, added rtl8139 and ne2k-pci support, and, last but not least, added dumpe2fs and debugfs (but not yet manpages).
All of which has freed up 37 sectors, so I'm open to ideas as to what to do with all the free space. -Tom
