Description of the issue (ideally so that others can reproduce it):
If the NFS server is running AIX, BACKUP_OPTIONS="nfsvers=3,nolock" has to be specified.
This also works fine when using OUTPUT=ISO and BACKUP=NETFS.
However in case of OUTPUT=PXE, mounting the NFS will fail with "mount.nfs: Remote I/O error" because in 800_copy_to_tftp.sh and 810_create_pxelinux_cfg.sh there is no $BACKUP_OPTIONS specified when "mount_url" is issued.
Another solution would be to create a new option like: PXE_TFTP_BACKUP_OPTIONS and pass it to where it is needed.
I am opening this issue as I am not sure if this is a bug or a feature or maybe I have overseen something...
Workaround, if any:
Add $BACKUP_OPTIONS to the line with mount_url in 00_copy_to_tftp.sh and 810_create_pxelinux_cfg.sh
