Tue Nov 22 00:47:35 EST 2011
It add support for using *.sfs images via NFS.
It must be located after archiso_pxe_nbd in mkinitcpio.conf, in that way
NBD is the default.
New boot parameters:
archiso_nfs_srv=IP:/path
Set the NFS IP and path. Accepts ${pxeserver} as IP.
archiso_nfs_opt= Sets NFS mount opts (comma separated)
Defaults to:
port = as given by server portmap daemon
rsize = 1024
wsize = 1024
timeo = 7
retrans = 3
acregmin = 3
acregmax = 60
acdirmin = 30
acdirmax = 60
flags = hard, nointr, noposix, cto, ac
