Where do you put Mount dependencies in systemd?
Systemd fabricates services for mounts; stumbling only slightly if they have hyphens in them: So, it should be possible to use before, after, requires, wants and friends to ensure that a service doesn’t start without its dependencies. Add the relationship on the mount unit. Add the relationship on the service unit.
How is systemd mount similar to mount ( 8 )?
In many ways, systemd-mount is similar to the lower-level mount(8) command, however instead of executing the mount operation directly and immediately, systemd-mount schedules it through the service manager job queue, so that it may pull in further dependencies (such as parent mounts,…
When does systemd service execute after fstab Mount?
After putting it additionally inside “”Requires” the service mounts the device before starting it, if the device was not mounted. Thanks for contributing an answer to Unix & Linux Stack Exchange!
Is the NFS mount a show stopper for systemd?
NFS, not so much. In my experience, systemd will start services implicitly dependent on an NFS mount the moment the network comes up. The mount might be there, it might be there in a little while, it might never turn up. It’s not considered a show stopper like block devices are.
Why does Debian systemd say cannot add dependency?
1) On boot, a swath of errors “Cannot add dependency X to Y.target, ignoring: File exists” appears, however the system appears to boot normally. The errors are: 2) watchdog is not started any more by default, which causes the HW watchdog, initialized by a bootloader I won’t flash without JTAG access, to reset the system.
What’s the weird thing about systemd in Debian?
I have a Debian armel machine running wheezy, upgraded to Debian Testing today. As you can guess from the title, systemd is weird in two ways: 1) On boot, a swath of errors “Cannot add dependency X to Y.target, ignoring: File exists” appears, however the system appears to boot normally.
When does systemd start services implicitly dependent on NFS?
If a linux server boots and a block device isn’t available, it’ll drop into some sort of single-user mode. This was the way with init, and is the way with systemd. NFS, not so much. In my experience, systemd will start services implicitly dependent on an NFS mount the moment the network comes up.
