## Runit init scripts for Cromnix
2+
3+
This repository contains the runit init scripts for the Cromnix Linux
4+
distribution.
5+
6+
This work is based on Void Linux's
7+
[runit-void](https://github.com/voidlinux/void-runit). Patches to Void
8+
Linux's repo will also be applied here.
9+
10+
## Dependencies
11+
12+
- A POSIX shell
13+
- A POSIX awk
14+
- procps-ng (needs pkill -s0,1)
15+
- runit
16+
17+
### How to use it
18+
19+
To see enabled services for "current" runlevel:
20+
21+
$ ls -l /var/service
22+
23+
To see available runlevels (default and single, which just runs sulogin):
24+
25+
$ ls -l /etc/runit/runsvdir
26+
27+
To enable and start a service into the "current" runlevel:
28+
29+
# ln -s /etc/sv/<service> /var/service
30+
31+
To disable and remove a service:
32+
33+
# rm -f /var/service/<service>
34+
35+
To view status of all services for "current" runlevel:
36+
37+
# sv status /var/service/*
38+
39+
Feel free to send patches and contribute with improvements!
