  • Description of the issue:

After running rear rescue to test PXE boot, I get:

Welcome to GRUB!

                             GNU GRUB  version 2.02

   Minimal BASH-like line editing is supported. For the first word, TAB
   lists possible command completions. Anywhere else TAB lists possible
   device or file completions.
[grub>

If I use PXE_CREATE_LINKS=MAC,
I see two files in /srv/tftpboot/boot/grub2/powerpc-ieee1275:

01-42-37-cb-60-59-02
01-42-37-cb-60-59-03

I assume this should show up as grub.cfg-01-42-37-cb-60-59-03
not just the mac address.

In each file is:

menuentry 'Relax-and-Recover v2.4' {
insmod tftp
set net_default_server=9.5.110.188
echo 'Network status: '
net_ls_cards
net_ls_addr
net_ls_routes
echo
echo " Relax-and-Recover Rescue image"
echo "---------------------------------"
echo "build from host: hana-n4 (SUSE_LINUX 12 Linux-ppc64le)"
echo "kernel 4.12.14-95.13-default  Sun, 28 Apr 2019 22:28:41 -0500"
echo "BACKUP=NETFS OUTPUT=PXE BACKUP_URL=nfs://9.5.110.188/nfs"
echo
echo 'Loading kernel ...'
linux (tftp)/rear/hana-n4/hana-n4.kernel root=/dev/ram0 vga=normal rw  selinux=0 
echo 'Loading initial ramdisk ...'
initrd (tftp)/rear/hana-n4/hana-n4.initrd.cgz
}

If I use PXE_CREATE_LINKS=IP:
I see two files with the same information as above:

grub.cfg-09056E 
grub.cfg-09056E22

Either way, I do not see the text that should pop up and be able to run rear.
