Description Luiz Angelo Daros de Luca 2021-02-03 22:53:40 UTC 
Hello,

Although SUSE uses /boot/grub2/grub.cfg path, some distributions might use /boot/grub/grub.cfg (which seems to be the default one).

The issue is this file:
https://build.opensuse.org/package/view_file/Base:System/grub2/grub2-xen-pv-firmware.cfg?expand=1

It looks for /boot/grub2/grub.cfg or /grub2/grub.cfg but not /boot/grub/grub.cfg or /grub/grub.cfg. If you simply add those entries, it will still not work because this script is provided as a memdisk at (memdisk)/boot/grub/grub.cfg, which might match before the actual local filesystem while looking for grub.cfg.

I'm not grub expert but it looks like it should, somehow skip (memdisk) while looking for a grub.cfg file, either changing the logic or changing the memdisk grub.cfg file path.

BTW, legacy_configfile does not exists while there is legacycfg.mod but I don't know if they are the same:

grub> insmod legacy_configfile
error: ../../grub-core/fs/archelp.c:260:file
`/boot/grub/x86_64-xen/legacy_configfile.mod'
not found.
