Re: PXE Booting

Unknown error: code 45
boot: Input/output error

Error: NFS2ERR_OPNOTSUPP

sorry for non-ascii

The bootloader doesn't accept a "root=..." argument

RP (17), length 26: "nfs://10.1.1.1/srv/vm/mail"

The root path attribute only contains the path ("/srv/vm/mail"),
not a pseudo-URL. The NFS server host used is either the BOOTP/DHCP
server itself, or the IP you pass as "swap server" attribute (code 16).

The man page diskless(8) gives more details about the process.

Yes, it tries to mount "nfs" (the beginning of your pseudo URL).
