Hello Guixers !
I am adding some `menu-entries` to my bootloader-configuration.
From `$ info "(guix)Bootloader Configuration"`
‘device’ (default: ‘#f’)
The device where the kernel and initrd are to be found—i.e.,
for GRUB, “root” for this menu entry (*note (grub)root::).
This may be a file system label (a string), a file system UUID
(a bytevector, *note File Systems::), or ‘#f’, in which case
the bootloader will search the device containing the file
specified by the ‘linux’ field (*note (grub)search::). It
must _not_ be an OS device name such as ‘/dev/sda1’.
My problem is that `device` (or no device at all) does not seem to
work as expected. Whatever the `device`, guix produces an identical
`search --file…` grub menuentry.
Attached are 3 configuration test entries and their resulting
`menuentry` in grub.cfg. Not sure how to produce a "bytevector"
for the UUID though, but at least the test with a label (literal
string) should produce something like :
"search --label --set debian-stable"
Correct ? Or do I miss something ?!
Thanks for you time !
