Isn't this part of the new paradigm:
"The linux desktop is dead, long live the linux powered gadget"

- Gnome cuts down features
- Gnome demands kernel embedded dbus from systemd to better support user apps
- Gnome logind
- Gnomes touch screen layout
... etc

I would expect better desktop support from alternatives like Xfce. What about Mint-gtk3?
Qt based razor-qt, now working together with lxdm-qt, which will provide the long discussed Qt experience without semantic-desktop ...

The fat projects (kde,gnome) soonishly will change their session startup into a systemd-user modular design. This will starve startx without pam. On the server side Kernel developers demand from systemd to provide the only instance for to change cgroup resources of virtual vms. Debian has decided against openrc ("too little too late") and is in preparation of default systemd-init...

Do you think Gentoo maintainers keep up against upstream?

I'm running xfce4, but also use a lot of gnome stuff. I tried getting around all the dependency problems before coming across this thread. My inclination is to attempt to get my system working in the way that the world seems to be moving. If I understand things correctly this means using systemd. An attempt to merge systemd gives

This wiki helped when I tested systemd out on another install:

The really important parts are to make sure your kernel has the right options enabled and the BIG one is to make sure to set the init= value at boot (although if you're using grub you could always add this manually after your system won't boot)

Thanks that link was useful. I'm still not clear if I can uninstall the blockers, and I'm not clear on what needs to be done when using grub2 as opposed to grub.

Thanks, when all else is cleared up, I'll add this

If you have the multislot flag disabled grub2-mkconfig and /boot/grub2 become grub-mkconfig /boot/grub. I updated that the other day with the new use flag and my system was briefly unbootable! When I did the switch I unmerged those and immediately emerged systemd and did not have trouble. If you're super paranoid have the gentoo livecd on standby and chroot to reinstall udev if something goes badly haywire (also worth keeping one around for accidentally unmerging portage or python. I know when I tried it and I had all that set up I uninstalled udev, installed systemd, then enabled the systemd global use flag and emerge -uDNav @world to recompile packages for the new flag.

I've decided to give this a try, and while I'm in the process of trying emerge things, I've had to emerge -C a few, but now I'm stuck. I get this blocker

I just disabled the consolekit use flag, recompiled the stuff that needed it, then emerge -C consolekit. Probably best to do that from outside an X session just in case it makes things go wonky inside a desktop session.

Well I bit the bullet and it has bitten me back. My system will boot, and I can startx as root, but the usual start using xdm and slim (as I recall) does not work. Right now a bigger problem is that I have no ethernet. (I'm posting this from a laptop, that was just configured to use the DSL modem.) ifconfig shows only "lo:". If I try to start /etc/init.d/net.eth0 it say net.eth0 is already starting. Apparently this takes forever. I'd really appreciate suggestions on how to track down these problems. Thanks,
Fred

hmm, I don't use xdm/slim so I don't have anything there, I usually just log in at the command prompt since I like to run updates and other things from there before starting a desktop. eth0 is probably systemd's new network naming scheme. Some time ago they changed the network naming scheme to something that would give persistent names to each NIC (as opposed to just naming them as they found them, which could get complicated if you have multiple network cards). This wiki article explains the scheme:

http://wiki.gentoo.org/wiki/Udev/upgrade

When I got hit with this upgrade i found was to run dmesg, at the bottom they have this: r8169 0000:03:00.0 enp3s0: link down (r8169 being my realtek ethernet). enp3s0 is the new persistent name my network card has instead of eth0/wlan0. Change your symlink from net.eth0 and that should work. That being said if you have networkmanager installed you shouldn't have net.anything in init.d and using systemd to start networkmanager which handles all of that. systemd handles services with the systemctl command so you'd do #systemctl enable NetworkManager.service.

I've tried to follow instructions, evidently not successfully. ifconfig now shows

I have removed 10-network-rules, renamed all the netx to ethx in /etc, and now I have a network on my main machine. But shorewall does not start, instead says "shorewall is already starting". I decided to go back to my laptop as I didn't want my main machine running without a firewall. After rebooting my main machine the ethernet ports were scrambled, so something needs to be done to tie them down. And I'd really like some idea of where to start in getting shorewall started. Is there a chance that I need to go back to netx in place of ethx, and just delete /etc/udev/rules.d/80-net-name-slot.rules?

Hmm don't use shorewall so its beyond me, but are you starting it through init.d scripts or systemctl commands? Init.d doesn't work in systemd you should do everything through systemctl

Thanks, I have enabled xdm and shorewall. The system now boots into my normal xfce4 environment -- that's good. Shorewall fails to start, but I think that is due to my network rules being messed up. I think I can get all my services started, but of course still no network.
