[systemd-devel] Help: Questions regarding systemd service order

[Tony Rodriguez]

Hoping I can accomplish the following via a simple UNIT modification or 
service script?


Questions:

A)  How can my service always runs "last" within local-fs-pre.target?

For Example:

Need my service to always run last within the local-fs-pre.target, even 
if others add another services later within local-fs-pre.target. Still 
want my service to always run last within this local-fs-pre.target.

Note: I will not know services others may later add within the 
local-fs-pre.target


B) How can I make my service run after all .mount(s) within 
local-fs-pre.target, before local-fs.target, especially if I don't know 
all the .mount(s)?  The .mount files are located within 
/var/run/systemd/generator/*

ls -l /var/run/systemd/generator/*.mount
-rw-r--r-- 1 root root 390 Nov 12 00:59 
/var/run/systemd/generator/boot-efi.mount
-rw-r--r-- 1 root root 449 Nov 12 00:59 
/var/run/systemd/generator/boot.mount
-rw-r--r-- 1 root root 428 Nov 12 00:59 
/var/run/systemd/generator/home.mount
-rw-r--r-- 1 root root 239 Nov 12 00:59 /var/run/systemd/generator/-.mount
-rw-r--r-- 1 root root 424 Nov 12 00:59 /var/run/systemd/generator/tmp.mount
-rw-r--r-- 1 root root 241 Nov 12 00:59 /var/run/systemd/generator/usr.mount
-rw-r--r-- 1 root root 424 Nov 12 00:59 /var/run/systemd/generator/var.mount

-rw-r--r-- 1 root root 424 Nov 12 00:59 
/var/run/systemd/generator/test.mount


Appears the UNIT section doesn't support a wildcard for .mount(s)

This doesn't work

#After=local-fs-pre.target *.mount

The following works, but have to hard code mounts. Would like to 
dynamically populate mounts for "After=" within my service file.

After=local-fs-pre.target boot.mount boot-efi.mount -.mount usr.mount 
var.mount tmp.mount home.mount
Before=local-fs.target

[Unit]
Description=mytest.service
DefaultDependencies=no
Wants=local-fs-pre.target
After=local-fs-pre.target boot.mount boot-efi.mount -.mount usr.mount 
var.mount tmp.mount home.mount test.mount
Before=local-fs.target
