This does not work:
open("/dev/cfs0", O_RDWR) = -1 ENODEV (No such device)
mount("coda", "/mnt", "coda", 0xc0ed0000, 0xbffffc04coda_read_super:
Bad file
coda_read_super: device index: 0
coda_read_super: No pseudo device
) = -1 EINVAL (Invalid argument)
_exit(-1) = ?
:-(. [I attached full source to my mount utility.]
