>Description:
When the BOOTP option is included in the kernel config, the system will not
boot unless the server provides a root path. The presence or absence of
the BOOTP_NFSROOT and ROOTDEVNAME= options has no effect on this behavior.
It should be possible to specify BOOTP and ROOTDEVNAME without BOOTP_NFSROOT
so that the kernel obtains IP-related information from the server and then
mounts root from the path specified with ROOTDEVNAME. It may be reasonable
and useful to use any server-provided path as a fallback if ROOTDEVNAME
doesn't work (i.e., store the server-provided name in rootdevnames[1]).
