[gentoo-user] Systemd systemctl : Failed to get D-Bus connection

[gentoo-user] Systemd systemctl : Failed to get D-Bus connection

Hi,
	Wanted to see whats all the fuss about so I tried installing Systemd on a 
laptop. following the guide on wiki.gentoo.org [1]. 

But I am having trouble running systemctl to configure the services I want 
started. Heres what I get (both as root and as a normal user).

# systemctl --all --full
Failed to get D-Bus connection: No connection to service manager.

I know Dbus is running for sure.

$ ps ax | grep dbus
 2094 ?        Ss     0:09 /usr/bin/dbus-daemon --system
 2803 ?        S      0:00 /usr/bin/dbus-launch --sh-syntax --exit-with-
session
 2804 ?        Ss     0:06 /usr/bin/dbus-daemon --fork --print-pid 5 --print-
address 7 --session

I tried booting with systemd to see what happens. It starts booting fine up to 
the point where it starts mounting the partitions. It just stops after 
mounting my /home partition. Nothing works at this point apart from a hard 
reboot. My partitioning is simple separate partitions for boot, home, root and 
the portage tree (all ext4). No separate /usr (phew). Also I do not have an 
initramfs.

What am I missing? do I need to modify any of the systemd config files? etc?


Here are the details of some of the packages.
 
sys-fs/udev-182-r2 (gudev hwdb keymap openrc rule_generator -build -debug -doc 
-floppy -introspection -selinux -static-libs)

sys-apps/systemd-43 (acl pam tcpd -audit -cryptsetup -gtk -lzma -plymouth -
selinux)

Thanks.

This will only work if you boot into systemd. Otherwise it doesn't.

Can I see your kernel command line as specified in /boot/grub/grub.cfg
(or /boot/grub2/grub.cfg)? The whole GRUB config would be useful.

Also, a cat /etc/fstab should shed some light on the issue.

Oh the wiki page instructed me to configure systemd before enabling it .. 
weird.

Ok after reading your mail I looked into my fstab and tried disabling 
everything one by one. Turns out this line in my fstab was the culprit.

#tmp in ram
none /tmp tmpfs defaults 1 2

Found this bug report [1] and so I changed the above entry to 

#tmp in ram
tmpfs /tmp tmpfs defaults 0 0 

works fine now. Like the fast boot and shut down.

Thanks for the hint.
