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

[Bone Baboon <bone.baboon@disroot.org>]

I have been able to execute this command
`echo "0" > /sys/class/graphics/fbcon/cursor_blink`
with a system that was using `runit` as it's initialization
system. The command was executed during stage 1 of runit's system
initialization.

Is there an equivalent to runit's stage 1 for Shepherd?

Thank you for bringing this kernel argument to my attention.

It looks like there are three settings to choose from:
https://www.kernel.org/doc/html/v4.15/admin-guide/kernel-parameters.html

`-1` and `1` both are blinking cursors. `0` is no cursor at all.  The
challenge with no cursor at all is that it lacks the visual feedback of
where the cursor is located.
