util-linux doesn't seem to ship /bin/more on non-linux. Upstream indeed
added UL_REQUIRES_LINUX([more]) since the addition of using signalfd,
which is Linuxish.

That's needed, yes.

That one is just a warning.

Not sure how your system looks like exactly. One issue we have is that
the debian-kosher way to run things is not the same as the hurd upstream
way to run things. Normally what happens is:
startup/startup.c's `tries' array starts with LIBEXECDIR "/runsystem",
i.e. /usr/libexec/runsystem, which symlinks to /etc/hurd/runsystem,
which symlinks to /etc/alternatives/runsystem, which symlinks to
/etc/hurd/runsystem.sysv, which doesn't look at /usr/libexec/rc at all.
All of this is supposed to be shipped by the hurd package, either from
the tarball or as an alternative, not sure why (I guess) your
alternative is not being set?
