Thanks for the info. Did it on world and got

-------------------------
-> USE="pulseaudio sqlite libkms cups apng minizip hwdb" emerge -vp
--newuse --tree --update --deep world

These are the packages that would be merged, in reverse order:

[snip]

[blocks B      ]  <sys-fs/udev-186 ("<sys-fs/udev-186" is blocking
sys-fs/udev-init-scripts-23)
[blocks B      ]  <sys-apps/sysvinit-2.88-r4
("<sys-apps/sysvinit-2.88-r4" is blocking sys-apps/util-linux-2.22.2)

Total: 126 packages (91 upgrades, 12 new, 6 in new slots, 17
reinstalls, 1 uninstall), Size of downloads: 989,597 kB
Conflict: 7 blocks
------------------------

I have udev-171 at the moment and I have read and followed the
instructions in the eselect news for the udev upgrade. I would
appreciate any pointers on how to deal with this particular blocking.

Thanks,
