BTW, I think some older systems might not know how to look for partuuid, (especially beyond the intial boot device?) and it could be worth trying plain uuid instead. I suspected such a stiutation when I got a not-found in the past, but did not diagnose it unambigously. --8<--aside BTW2, I am using refind to multiboot, and consider my shooting myself in the foot (clobbering my efi partition with unintended grub install) as a kind of usability-bug, which I am tempted to use as rationale for posting to this list (but not hijacking this post further ;-) Would that be ok, or should I join guix-help as well? I am getting more email traffic than I am used to :) ... (I would like to mount a losetup file partition as a target for grub bootloader install, and thereby capture initrds etc for manual (at first ;-) transfer into my refind efi vfat file tree.) --8<--aside-- > The contents of by-id and by-partuuid don't change when the install DVD is inserted, > so I assume that the contents of those directories are not related to the DVD. > > > > You could also type in the recovery > > Guile repl that opens: > > > > (use-modules (ice-9 ftw)) > > (scandir "/dev/disk/by-id") > > (scandir "/dev/disk/by-uuid") > > (scandir "/dev/disk/by-partuuid") > > > > and maybe: > > > > ,L bournish > > cat /run/booted-system/etc/fstab > > > The keyboard/usb ports do not function at this point in the boot, > despite working earlier in the boot during EFI and GRUB.  I > can see but not type in the recovery Guile repl. > > > > > Regards, > > Florian > Regards, Bengt Richter
