This is from Andreas' suggested patch for nbd root, where this is the
third supported method of booting nbd. I think we should DROP this. The
reason for this is it used to be necessary to define a specific nbd
device number because old versions of nbd-client did not have a method
to detect if a nbd device is already connected and in-use. Modern
versions do not have this problem. Code using it simply iterates looking
for the first unused nbd device.
The ability to specify a nbd mount point with cmdline should be using
the new syntax. We should drop this old syntax because it is redundant,
and more error prone.
While I don't care so much if the other legacy methods go into dracut, I
might suggest strongly against including this one. In addition to the
other reasons:
* It was never used with DHCP root-path in the past.
* It relied on other hard-coded things that you don't see to specify the
filesystem type and aufs/unionfs layering on top. Note that it doesn't
include filesystem type and mount options.
