Tell me a little about it
@RL_Dane Well...
- It's incredibly fast
- Barely uses any memory
- Uses shell scripts to create services, but aren't has asinine as sysvinit scripts are (Runit services are one line, versus sysvinit init, which can get up to 40 lines of shell for a simple daemon)
- Logging is incredibly easy compared to sysvinit
- Works on top of any existing init system if you don't want it to replace the old one outright. Yes, it can even be used alongside systemd.
- Very unixy way of managing services. It's basically just a bunch of symlinks and
touchfiles.
@RL_Dane NetBSD's is still my favorite, but the two don't really compare. Runit is definitely more Service oriented than NetBSD, which is more daemon oriented
I'm not sure I understand the difference XD
JdeBPMewburn rc still uses PID files, a mechanism that people knew to be broken back in the middle 1980s. daemontools-family systems like runit do not.
There's no universal agreement on what a "service" is as opposed to a dæmon. But the concrete differences between the systems start with PID files, and continue with chain loading, logging, and composition.
