# It'd be nice if this could share rules with 99-block.sh, but since
|
|
# the kernel side adds nbd{1..16} when the module is loaded -- before
|
|
# they are associated with a server -- we cannot use the udev add rule
|
|
# to find it
|
|
#
|
|
# XXX actually we could, if we move to root=XXX and netroot=XXX, then
|
|
# you could do root=LABEL=/ nbdroot=XXX, or netroot=nbd:XXX
|
|
#
|
|
# However, we need to be 90-nbd.sh to catch root=/dev/nbd*
|
|
#
|
|
# Preferred format:
|
|
# root=nbd:srv:port[:fstype[:rootflags[:nbdopts]]]
|
|
#
|
|
# nbdopts is a comma seperated list of options to give to nbd-client
|
|
#
|
|
#
|
|
# Legacy formats:
|
|
# nbdroot=srv,port
|
|
# nbdroot=srv:port[:fstype[:rootflags[:nbdopts]]]
|
|
# root=dhcp nbdroot=srv:port[:fstype[:rootflags[:nbdopts]]]
|
|
# root=nbd nbdroot=srv:port[:fstype[:rootflags[:nbdopts]]]
