systemctl (Fedora 17) and interacting spawned processes's consoles
- by Sean
Introduction
I've recently upgraded to Fedora 17 and I'm getting used to the newer systemctl daemon manager versus shell init scripts.
A feature I need on some of my daemons is the ability to interact with their consoles because unclean shutdowns not initiated by the process itself can cause database corruption. So, performing a systemctl stop service-name.service for example might cause irreversible data loss.
These consoles read user input through stdin or similar methods, so what I've been doing on my old OS is to place those daemons foregrounded in a screen session, and I suspended that screen session with ^A ^z. It's also worth noting that I've now made systemctl do this automatically if the computer reboots, but it still doesn't solve my potential data corruption problem I'm trying to avoid.
My Question
Is there a way to use systemctl in order to directly interact with the console of processes it spawns? Can I hook a process through systemctl to get access to its console?
Thanks
You guys always give great answers, so I'm turning to you!
