First of all I 'm new user of these distribution list and I do not know if this is the correct place to post my problem and ask for help. If not my apology and please refer me to to the correct place. I' m using Arch now for several years on a desktop and a laptob without severe problems. Few days ago I changed to systemd both on the laptop and desktop. For the laptop all went fine and I' m able to boot using systemd and the system is up and running as before. The only difference between laptop and desktop is that the /home partition on the desktop is on a SW raid My problem: When booting with init=/bin/systemd I have the following phenomenon: Job dev-mapper-nvidia_cjjcaiiep1.device/start timed out and booting stops and I'm in a rescue shell. my /home partition is not mounted. /dev/mapper/nvidia_cjjcaiiep1 exists. Systemctl start dev-mapper-nvidia_cjjcaiiep1.device gives the same result timeout. and my /home is not mounted When I do a manual mount of the /home partition mount /dev/mapper/nvidia_cjjcaiiep1 /home /home is mounted Systemctl default my system resumes booting and finally comes online. I 'm new to systemd so if someone can be so kind to give me some hints how / where to start searching for the problem or maybe the problem is already known ... Thanks in advance. Fred
