Hi, that's great and I would love to see this on OpenWRT/LEDE - maybe as optional dependency - runit / runsvdir is afaik already in busybox. Personally I'd would love to have some ability to use procd facilities with runsvdir/runit. ubus access, uci triggers... but I'm not sure what would be a good way to implement that - I guess something like a ubus<->runit shim could do the trick. Maybe there could be some support for runsvdir in procd - but at the moment these tools can coexist fine. Personally what I'm missing in procd and what runit provides is the following: - runsvdir like funktionality. e.g. on Freifunk firmwares you have to run do some maintaince or check tasks occasionally and cron is not really great - beeing able to use something like http://code.dogmap.org/runwhen/ would be great. runwhen = cron+at but better ;) - more flexibility for checks. busybox runit has sv check - http://smarden.org/runit/sv.8.html - where a script can be triggered regulary and the exit code decides wether to restart the service or not - this allows for better checks than just pid exists - sometimes software get's stuck but appears to be working fine from the procd/system perspective. - more flexibility for logging I don't think it should be the default but it would be great to marry procd and runit on LEDE. I'm also aware that this is not trivial but making ubus/procd/netifd and runit talk to each other i.e. restart a service running with runit on a netifd change would be great! So TL;DR: procd is fine for init but having runit/runsvdir easily usable would be a nice feature to have! ..just my 0.02c greetings from Weimar, Martin _______________________________________________ Lede-dev mailing list Lede-dev@lists.infradead.org http://lists.infradead.org/mailman/listinfo/lede-dev
