Hello,
I've got a somehow silly question:
Am I right to think that a service unit I wrote meant to format and
mount a localdisk at boot having the following properties :
Wants=local-fs.target
Before=local-fs.target
+ DefaultDepenencies=no may be racing against udevd in a way the device
(/dev/nvme0) would not be there yet ?
Yes.
If so, would adding After=systemd-udevd suffice ?
No.
Either invoke your service from within udev rule (SYSTEMD_WANTS or
even systemctl start), or configure your service with
Requires=dev-nvme0.device
After=dev-nvme0.device
Actually, you probably want to do it even when invoking by udev rules.
This assumes that /dev/nvme0 is reasonably stable. You may want to use
some other available /dev/disk/by-... stable alias.
Ok, thanks for your reply.
