Re: PXE Booting

[Pierre <pbraun%nethence.com@localhost>]

I encountered similar issues with netbooting before, your error message is close to

Unknown error: code 45
boot: Input/output error

Error: NFS2ERR_OPNOTSUPP

I solved it by enabling disabling subtree check in the nfs export setup (https://pub.nethence.com/booting/pxe.netbsd).

sorry for non-ascii

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).
