This patch is to solve the following circular dependency problem.
systemd -> dbus -> libsm -> e2fsprogs -> util-linux -> systemd
libsm doesn't have any dependency on e2fsprogs. It might be some
dependency
on util-linux's libuuid, controlled by configure options. So
e2fsprogs should
be removed from the DEPENDS variable.
Ideally, we should add a PACKAGECONFIG for 'libuuid' for libsm.
However, if
libsm depends on util-linux, we would have the circular dependency
described
above. That's why this patch explicitly set '--without-libuuid' in
EXTRA_OECONF.
libsm would still be working well because it would fall back to an
internal
algorithm to do the uuid stuff.
Maybe libuuid should get its own recipe. It can be built from the
util-linux sources. Other packages can then just depend on that
libuuid recipe instead of util-linux itself.
Only problem would be util-linux I guess, you'd get two providers for
libuuid.
I thought about this approach too. I didn't use it because of the
following reasons.
1) IMHO, we haven't reached a point that a separate libuuid recipe
becomes a necessity.
Splitting a recipe may need more compelling reasons.
2) If we are really going to do so, I think we may need an RFC in other
patches. I don't want to make a patchset regarding package upgrades
involve too many changes.
