You can configure the sysfail boot entry using the bootctl command:
$ bootctl set-sysfail sysfail.conf
The value will be stored in the `LoaderEntrySysFail` EFI variable.
The `LoaderEntrySysFail` EFI variable would be unset automatically
during next boot by `systemd-boot-clear-sysfail.service` if no
system failure occured, otherwise it would be kept as it is and a system
failure reason will be saved to `LoaderSysFailReason` EFI variable.

I think the current behaviour of not doing EFI variables when we are run
in a container makes a ton of sense, but in some cases it's useful to
do EFI var setup even when a set of namespaces is set up for us, for
example to recover a hosed installation from a rescue disk.
While we are at it, let's remove some duplicate checks, and
systematically output information why we skip various operations.
