After today's emerge-webrsync, I have found out that usual # emerge --update --deep --with-bdeps=y --newuse --ask world does not work, trying but being unable to emerge systemd.
As I have found out, the reason for it was that upower suddenly decided that it needs systemd but, for some (lucky :) reason, it could not be emerged as my system uses OpenRC. The latest news said the following: "UPower discontinued hibernate and suspend support in favor of systemd. Because of this, we have created a compability package at sys-power/upower-pm-utils which will give you the old UPower with sys-power/pm-utils support back. Some desktops have integrated the sys-power/pm-utils support directly to their code, like Xfce, and as a result, they work also with the new UPower as expected. All non-systemd users are recommended to choose between: # emerge --oneshot --noreplace 'sys-power/upower-pm-utils' or # emerge --oneshot --noreplace '>=sys-power/upower-0.99.0' However, all systemd users are recommended to stay with sys-power/upower." However, that news did *not* say that without # emerge --oneshot --noreplace 'sys-power/upower-pm-utils' it is impossible to update the system even if you use xfce. Only after executing the last command, which installed upower-pm-utils and unistalled upower, the # emerge --update --deep --with-bdeps=y --newuse --ask world worked as desired. upower was not in my world file, so I think it's a some kind of a bug.
