Hi Immo and All,
thanks for the heads-up, answer inline.

1. is based on Slackware and uses the same layout, so I forward this answer to
its maintainer, Patrick J. Volkerding (he is not subscribed to this list as far
as I know).
2. as Slackware, Slint does not uses systemd as its init system so far but
includes kind of a compatibility layer, mostly elogind. We also use eudev
instead of udev.
3. As Slackware, Slint has an "unmerged-usr" layout so far, i.e. bin, sbin and
lib* are not symlinks to their counterparts under /usr.
This being said I do not know which changes Patrick intends to do for the next
Slackware version on this respect but intend to follow suite with Slint.

What I fail to grasp is the possible consequences of this change for
distributions not using systemd as their init system. Any clue on that is
welcome. If understand well, as long as we do not change our layout we do not
need that our (custom made, not using dracut) initramfs implements the changes
mentioned in https://fedoraproject.org/wiki/Features/UsrMove
