[SOLVED] Can't start mariadb and avahi anymore, cannot connect users

Hi
Yesterday, it seems i broke something in my system:
Arch is updated. Linux-lts kernel.
I can't connect users in tty. Mariadb and avahi-daemon don't start at boot. I can't start them manually too using systemctl.
But I can connect as root.
Other services are started normally: ntpd, connmand, bumblebeed, syslog-ng or metalog, sshd.
I don't use any login manager like gdm.
I don't use X, i use only tty, wayland and enlightenment-git.
I remember i killed by hand yesterday in the evening ssh-agent processes. Problem came after that but may be a coincidence...
It's a permission issue.
Precision: I used without any problem since january to yesterday, each day, last pambase-20190105.1-1 .

I have good symlinks in /var:

ls /var -1 -p
cache/
db/
empty/
games/
lib/
local/
lock -> /run/lock
log/
mail -> spool/mail
net-snmp/
opt/
run -> /run
spool/
tmp/

I posted journalctl -b here

Please edit your post to use code tags around the terminal outputs.

Please also post a full journal, without -x.

Re: [SOLVED] Can't start mariadb and avahi anymore, cannot connect users

Thanks for fixing up your first post, however, you forgot to add code tags around your ls output. Also, please don't use pastebin.com or upload truncated logs. See https://wiki.archlinux.org/index.php/Li … in_clients -- make life easier for yourself and use a CLI pastebin client and a more accessible pastebin service.

That all said, it looks like your /run directory is not accessible by non-root users. Please post the output of

# ls -ld /run
# pacman -Qkk filesystem

Again, please use code tags for this.

Re: [SOLVED] Can't start mariadb and avahi anymore, cannot connect users

I found similar problem here https://bbs.archlinux.de/viewtopic.php?id=31207
They solved issue doing:

chmod 755 /

In my case

 ls -ld /
drwx------ 19 root root 4096 Feb 20 16:55 /

I checked my other computer without problem:

 ls -ld /
drwxr-xr-x 16 root root 4096 Feb 19 20:55 /

It's crazy, I have not good permissions on /
I solved the problem with 

chmod --preserve-root 755 /

Thanks for your help!
