Re: Difficulty mounting ext3 partitions with labels...
Hi,
Found the answer to my own above question by examining e2fsprogs source
(didn't think to make devfs connection), thus replying to myself for benefit
of list archives. Quoting from Richard Gooch's devfs FAQ:
Mount by volume LABEL=<label> doesn't work with devfs
Most probably you are not mounting devfs onto /dev. What happens is that if
your kernel config has CONFIG_DEVFS_FS=y then the contents of
/proc/partitions will have the devfs names (such as
scsi/host0/bus0/target0/lun0/part1). The contents of /proc/partitions are
used by mount(8) when mounting by volume label. If devfs is not mounted on
/dev, then mount(8) will fail to find devices. The solution is to make sure
that devfs is mounted on /dev. See above for how to do that.
Take care,
Daniel
