This release extends USE=-systemd's logic to update a static version-less file or symlink to USE=+systemd. And fixes installing refind icons for .old entries and version-less entries. Effectively it becomes possible to "static" efistub boot, complementing the existing support for "dynamic" efistub booting (via virt-firmware and uefi-mkconfig). It does require a manual step in the form of creating this version-less file/symlink, subsequent re-installs will then update the file/ symlink (this mirrors how this was already implemented for USE=-systemd).

# Only select one flag that sets "layout=", except for uki since grub,

# the uki layout.
|
|
#
|
|
# Refind does not set a layout=, it is compatible with the compat, uki
|
|
# and efistub layout. So block against only grub and systemd-boot.
|
|
#
|
|
# systemd-boot could be made to work without the systemd flag, but this
|
|
# makes no sense since in systemd(-utils) the boot flag already
|
|
# requires the kernel-install flag.
|
|
#
|
|
# Ukify hooks do nothing if the layout is not uki, so force this here.

|
#
|
|
# Only one initramfs generator flag can be selected. Note that while
|
|
# both dracut and ukify are UKI generators we don't block those because
|
|
# enabling both results in building an initramfs only with dracut and
|
|
# building an UKI with ukify, which is a valid configuration.
