Hey, that wasn't intentation. In fact it's a stupid brown-paperbag bug
only hidden by mount-by-label :)

Here's the fix:

--- 1.1/fs/partitions/devfs.c Sat Apr 19 20:57:36 2003

{
char dirname[64], symlink[16];

- if (disk->devfs_name[0] != '\0')
+ if (disk->devfs_name[0] == '\0')
sprintf(disk->devfs_name, "%s/disc%d", disk->disk_name,
disk->first_minor >> disk->minor_shift);

Somebody please apply this patch:

http://hypermail.idiosynkrasia.net/linux-kernel/latestweek/0150.html

It's still not in 2.5.68-bk5. It's a major headache for everybody who
tries to use devfs with the current kernel.

Sorry, I sent this to Linus two times but he hasn't applied it yet :P

Linus, could you please apply this patch so all thos poor devfs
users get their disks back?

I confirm that the new patch is working for me just as well as the old
one.
