Re: How to create a service for contents of arbitrary file

[Julien Lepiller]

No, Shepherd doesn't have a notion of stages. You can make it run a command at 
startup by using a normal service though. I use one on my server to set up 
static networking with ipv4 and ipv6 by running iproute. See 
https://git.lepiller.eu/system-configuration/tree/-/modules/config/network.scm

Maybe there's another kernel argument you could use?
