Norbert, All,

How has the situation with upstream evolved since last time the topic
was raised here:
    https://lore.kernel.org/buildroot/cover.1545814334.git.yann.morin.1998@free.fr/#t
and especially the sub-thread:
    https://lore.kernel.org/buildroot/d38239f86f99924e87dcb6e045b2de3ac0cb435f.1545814334.git.yann.morin.1998@free.fr/

As far as I know (and understand), upstream has decided to tie the build
of systemd-boot (formerly the standalone gummiboot) to the build of the
rest of the systemd suite; they did not accept to make it possible to
only build systemd-boot to use it outside the systemd ecosystem.

From Buildroot's perspective, allowing to build systemd without it being
an init system, and without the possibility to just build systemd-boot,
is asking for troubles down the line.

The triviality of your patch does not make it possible to only just
build systemd-boot; instead, it still builds the whole systemd suite,
which hints that upstream did not make it possible to do separate
builds.

So, unless things have evolved substantially, I am not very fond of
alowing this, and stand by the decision that was made back then (i.e.
abide by upstream decision and tie systemd-boot to the systemd
ecosystem).

Regards,
Yann E. MORIN.
