[fuse-devel] LVM, NBD client support for mountlo

[Charles D. <Cha...@me...>]

Howdy. I'm looking at adding LVM and NBD support to mountlo (to allow it 
to mount partitions off of qcow2-formatted virtual machines' hard 
drives, served by qemu-nbd). This looks like it will involve the following:

  - Kernel rebuild to add device-mapper and networking support
  - Addition of lvm, nbd-client
  - Switch userland to busybox with only iproute2, mdev [udev-alike], 
mount/umount enabled

...I'm looking at using buildroot to put together this minimal userland 
(uClibc-based, shared libraries stripped to contain no unneeded symbols).

NBD, at least, should run fine with UML's userland networking only; NFS 
might not; consequently, I'm not sure whether to bother trying to 
support it.


Thoughts? Is there anything I'm missing here? Would this functionality 
be desired upstream?
