I need to set some flags in order to boot as described here: https://www.qubes-os.org/doc/uefi-troubleshooting/ My settings look like this: $ efibootmgr -v BootCurrent: 0000 Boot0000* Qubes HD(...)/File(\EFI\qubes\xen.efi)p.l.a.c.e.h.o... which causes awk to get confused and think my $EFI_DIR should be: /EFI/qubesp.l.a.c.e.h.o.l.d.e.r. ./.m.a.p.b.s. ./.n.o.e.x.i.t.b.o.o.t. This causes the script to later bail: if [ ! -d "$EFI_DIR" ]; then # non-EFI system exit 0; fi So my xen.cfg did not get new entries when installing dom0 kernel packages.
