However as David mentions the block device support thing is an issue here. What is a reasonable way to allow a cramfs partition to access the device directly, like the patch that I wrote, and be picked up in a reasonable way by the init system? (Current system does some non-cool things like find out it's cramfs from /dev/rom , and within cramfs never accesses that block device anymore..., it's sort of silly, and _not_ the right way to do it.) Thanks, Shane Nay. (Patches referenced here can be found at: ftp://ftp.agendacomputing.com/pub/agenda/testing/CES/patches/ , contributed by various authors: Rob Leslie, Brad Laronde, and myself.
