A good question, and not specific to systemd, so I don't want to
pollute the list archives too much on this matter.
'All' I did was remove many RPMs that I arbitrarily deemed
unnecessary.
I came up with a heavily trimmed-down list of SLES RPM for my SLES12
Sp5 environment.
I successfully installed a server using just that trimmed-down list;
yay me!
I then explored 'upgrading' a running (slight older) SP5 box, using
this trimmed-down list. A purposeful side effect was to uninstall
RPMs not in that trimmed-down list.
This latter box begins to boot, and gets at least as far as loading
the initrd image, before hanging.
Boot with "systemd.debug-shell" and use tty9 to investigate from the inside.
