Or would it be helpful to just send the patches to the list? Hi Lewis it's cool to see you are interested in runit. May I ask whether you are using it for controls / EPICS? AFAIK there is no public repository for runit. You may want to ping Gerrit Pape personally to get his attention. His last message to the list is from march this year where he said he was "looking forward to do a maintenance release of runit eventually and [...] collecting patches".

You can also write your own specialised daemon with a simple shell script a la inotifywait -q -m ... | while true; do # get the next event: event=$(head -1) ... done I am using this method in a production system.

Hi, I was the one who told Lewis about sdnotify-wrapper and it seems I got it completely wrong: I had thought it was a wrapper for daemons that use the s6 notification mechanism to make them compatible with the systemd convention. Your description above suggests it does the exact opposite. Cheers Ben
Re: Path monitoring support in s6-services
Since it requires individual instances of inotifyd for each service(s) [which depends on multiple files/paths modifications) to get started] Have you tried it and noticed an impact on your boot times? (AKA: "Profile, don't speculate.") -- Laurent

Re: Path monitoring support in s6-services
inotifyd (or something similar) + s6-svc (or s6-rc)? Thought of the same but I have many such services;Just thinking of cpu overhead during the initial boot up. What makes you think this would have a noticeable impact on your CPU load? -- Laurent
