[archiso] Add PXE NFS support
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 :: Running Hook [archiso_pxe_common] IP-Config: eth0 hardware address 52:54:00:12:34:57 mtu 1500 IP-Config: eth0 guessed broadcast address 192.168.0.255 IP-Config: eth0 guessed nameserver address 192.168.0.218 IP-Config: eth0 complete (from 192.168.0.218): address: 192.168.0.90 broadcast: 192.168.0.255 netmask: 255.255.255.0 gateway: 192.168.0.218 dns0 : 192.168.0.218 dns1 : 0.0.0.0 rootserver: 192.168.0.218 rootpath: filename : :: Running Hook [archiso_pxe_nbd] :: Running Hook [archiso_pxe_curl] :: Running Hook [archiso_pxe_nfs] :: Mounting '192.168.0.77:/mnt/iso' ... 192.168.0.77:/mnt/iso/ on /run/archiso/bootmnt type nfs (rw,relatime,vers=3,rsize=524288,wsize=524288,namlen=255,hard,nolock,proto=tcp,port=65535,timeo=7,retrans=3,sec=sys,local_lock=all,addr=192.168.0.77) ...
