I have a working solution for this already in the vger CVS, half of it has
been already merged into 2.1.97, the other part might be soon.
Even with libc5, I can do anything I want with 43 disks attached to the
machine, like building ultra-large raid devices, etc.
There are two new system calls: xstat and xmknod, which have reasonably
sized entries (like 64bit sizes, 64bit dev_t, 32bit uids/gids, etc.).
Now, in order to use it with libc5, you'd need a hacked up mknod program,
which will check if you want to build minor > 255 and if that's true, use
the xmknod system call instead of mknod.
fdisk works without problems, the only problems I had were with raidtools:
I had to hack them up, so that they use xstat syscall to find out the minor
of the device and have added a new ioctl for creating a RAID, which takes
32bit majors and 32bit minors.
Cheers,
Jakub
