Re: [SOLVED] after upgrade to systemd only login as root is allowed
I recall seeing sometime ago people having problems with proper mounting and permissions due to your media-automount udev rule. It used to be in the udev or usb storage wiki but was taken out some time ago probably due to the problems caused by it after introduction of systemd.
Rules like this have always been problematic.

Re: [SOLVED] after upgrade to systemd only login as root is allowed
Your "drilling down" yields nothing of relevance or value. However, looking back...
[root@image1 ~]# ls -la /home total 40 drwxrwx--T 5 root root 4096 Dec 27 07:39 .Why does your /home have these bizzare permissions? Please fix this.
I don't know where the sticky bit came from...
I've disabled the udevrule and changed the permissions of /home to 755. But after a reboot it's all like before:

Re: [SOLVED] after upgrade to systemd only login as root is allowed
What do you mean? The permissions for /home are showing as 755 in the above. Is that what you get following reboot? If so, they haven't reverted.
The permissions on /, /boot are also bizarre, though, and should be fixed as well.

Re: [SOLVED] after upgrade to systemd only login as root is allowed
Hi falconindy/Dave,
drwxrwx--T 20 root root 4096 Dec 8 22:42 .Every user except root is forbidden from searching every directory in your filesystem -- this explains why polkit and your user are unable to login. Your / MUST be 755.
Your right! I guess my now disbled udev rule changed the permissions of /home, /boot,swap and / from 755 to 1770. As a interesting fact this was never a problem using sysinit mechanism but is erroneous using systemd! For the other readers: 1777 for /tmp is default and these settings is a must have.
Thanks for your analysis and help!!
But now is a question open: how can I transform the udev rule to be systemd compliant? Is there any documentation titled like "transforming udev rules to sytemd"?
As argyllcms in AUR has a udevrule, is there anything critical with this rule?
I've changed the appropriate mountpoints to 775, performed a reboot and now everything runs fine (until now)...

Re: [SOLVED] after upgrade to systemd only login as root is allowed
Please understand that systemd doesn't care about disk permissions any more or less than sysvinit, or any other init system. I don't know why you wish to continue to attempt to draw this conclusion, but I assure you that removing search access to all users but root for your entire filesystem is problematic and has absolutely zero bearing on what PID 1 happens to be at the time.
The far more logical conclusion to draw here is that sometime during your efforts to convert to systemd, you changed these permissions.

Well, I thinks the permissions changed by my udevrule during the upgrade to systemd. I had never before the disk partitions mounted additionally! under /media. Please have a look to my first findmnt output. I never touched the permissions of the four partitions manually without reverting to it's default.
But now it's the time for me to get more familiar with systemd...
best regards and a hapy new year,
