[uml-devel] Partitioning scheme for ubd's

[BlaisorBlade <blaisorblade_spam@yahoo.it>]

Since some time, we can get nice messages as ubda: unknown partition table on 
boot if we use ubd's normally, and even install UML on partitions for 
installs.

But there is a problem here:
1) device names are not consistent: if you want to use ubd[a-z], decide so and 
start the change(for 2.6 there's a lot more changes anyway, so it is a good 
occasion...)

2) if I do an install, I can partition the ubd's; but then, I won't be able to 
loop mount the file on the host(and if I'm in trouble, this ability is worth 
a lot). In fact, I've never partitioned the ubd's, but this meant a lot of 
trouble even to run Slackware install.

3) so, I thought this: since partitioning schemes are pluggable, it would be 
possible to fool it and turn the ubd's into partitions of a single disk. I.e. 
if I setup udb0, ubd1 and so on, they would be seen as three partitions of a 
single disk. But they are still different files, loop-mountable on host.

Would you ever accept this? The other possible solution(which would be 
cleaner) would be to teach, if possible, to the host kernel Device Manager to 
read a file as a bunch of partition with its table(I've heard of DM about COW 
files these days), and then to mount the partitions, but I don't know if it's 
possible.
