To fix this libdlm-3.1.5 needs a STABLEREQ .. any blockers I am not seeing here?
Only ~arch version of sys-fs/lvm2 is using clvm/cman so nothing is broken. $ cd /usr/portage/profiles/base/ $ grep lvm2 package.use.mask # we unmask them only for >=sys-fs/lvm2-2.02.98. <sys-fs/lvm2-2.02.98 clvm cman Moving to libdlm maintainers for normal stabilization. Nothing to do with sys-fs/lvm2.
