This builds on the NFS root work to allow other network methods to hook
into the parsing and network infrastructure. One network interface is
configured at a time, but if we don't find a root there, it may not be
unconfigured -- this should probably be added.
I implemented some of the legacy formats we talked about, but not all of
them, and I may not have them 100% correct. That handling has seen less
testing than the NFS methods I usually use. I have verified that this set
will work with root=dhcp w/ NFS, and no root, but nbdroot= for NBD.
I think we can offer some support for LVM/LUKS over NBD, but that's low
on my list at the moment -- it was more important to shine some light
on this to see if it gets burned up. Documentation would be another high
priority, as in the formats supported as well as the interfaces and
expectations of the handlers.
David Dillow (9):
nfsroot: move to same sort order as block methods
block root: split out resume parsing and udev rules
dracut: add cmdline hook
cmdline: cleanup handling and block: handler
resume: add support for labeled resume devices
dracut-lib: add source_all to library
netroot: add common handler for network root devices
nfsroot: move to netroot framework
Add NBD support
