[systemd-devel] Have I got circular dependencies?

[Wols Lists]

This is probably a classic "need a clue" problem ... my system has 
suddenly stopped booting properly, and I guess it's a problem with my 
custom systemd service.

Basically, I've configured my raid device on top of dm-integrity, so 
that needs to be set up before my /home becomes visible. I've tried to 
say my integrity.service needs to run before the mdadm and lvm services.

I also seem to remember a mention of dm-integrity in recent (the 
latest?) release notes?

The problem being I don't know what - or where - most of the system 
systemd services and files are.

Does all this output indicate a problem with my service? Can I just 
delete my "Before" line, bearing in mind that if the service doesn't run 
my /home won't appear? (mdadm and lvm pick things up if I run the 
service manually.)

And could this be why my service seems occasionally to get randomly 
killed on boot, leading the problem I described where /home has disappeared?

Cheers,
Wol
