Remove evms and lvm2 from default boot args (they cause hardware issues, so users should explicitly specify them); add NFSboot support patches by Thomas Seiler.

@ -241,6 +241,18 @@ Passes arguments to init on bootup.
\fBscandelay\fR=<...>
Pauses for 10 seconds before running devfsd if no argument is specified;
otherwise pauses for the number of specified seconds.
.TP
\fBip\fR=<...>
Normally used to tell the kernel that it should start a network interface. If present, the initrd will try to mount a livecd over NFS.
.TP
\fBnfsroot\fR=<...>
If present, the initrd will try to mount a livecd from that location. Otherwise the location will be deduced from the DCHP request (option root\-path)
.SH NETBOOTING
The initrd scripts have limited support for network booting.
This is activated if the ip=<...> kernel parameter was given. Please refer to the genkernel guide at http://www.gentoo.org/doc/en/genkernel.xml for more information.
The initrd scripts will extract any *.tar.gz files found in the \fB/add\fR directory of the livecd into the root filesystem during boot. This way its easy to extend a netbooted livecd i.e. with custom tools, or other kernel modules.
.SH REPORTING BUGS
If you believe you have found a bug in the genkernel scripts, then please
file a bug on the Gentoo Linux Bugzilla:
