Is #588675 (/ left as /dev/root) A Kernel Bug?
#588675 may not be all that severe, but does cause issues with multiple
packages. The issue is sometime between Debian Etch and Debian Lenny the
line for the root filesystem in /proc/mounts stopped listing the actual
device (/dev/sda1) started listing "/dev/root" instead.
One crucial ingredient I'm certain of is this requires a kernel that has
the drivers necessary to mount the root filesystem builtin and not be
using an initrd. Both reportted encounters with this bug involve kernels
that have been built from source.
I've got little idea of where the actual bug is lurking. I've got some
suspicion this may be a bug in the SCSI subsystem. The one machine I've
noticed this *doesn't* occur on is one where it boots with root on a MTD
device. I'll try to see if I can pursuade that machine to boot directly
onto it's USB device as root, to see whether or not it is due to being a
MIPS system (grr, emdebian.org being down is a problem).
