Hi all,

I don't know if this is right group...
But:
I have about 200-300 CD-ROM images, that I would like to mount
and export over Samba for Windows clients.

Now I do it with simple script:

mknod /dev/fileN 43 N
vnconfig /dev/fileN /somewhere/fileN
mount -t cd9660 /dev/fileN /somewhere-else/fileN

Problem is in generation of N numbers.
Now, I generate them, and I get:

0x1000E0
0x1000E8
0x1000F0
0x1000F8
0x200010
0x200018
...
0x800050
0x800058
0x800060
...
0x2000010
vnconfig: VNIOCATTACH: Device busy (this message is generated by mount)

Questions are: what is maximal number of devices I can configure,
and what is the key to generate numbers for special files.

TIA,

Piotr Patronik
