Anyway, I have been using doas instead of sudo for a while on servers, it’s rock solid if you don’t need some of the more advanced features of sudo.
Then stop doing that.
Don’t use bash, stick to #!/bin/sh, use shellcheck, wrap all variables in quotes, use command -v to check if a binary is available before trying to use it, and don’t use gnu specific things.
I don't think shell is a great language or even that good for configuration, but it is pretty simple and the quantity of footguns are similar to JavaScript.
My issue with systemd is not the configuration file/language, that bit is pretty cool. My issue is mostly with all of the half-assed auxiliary services they keep pushing and something is not quite right with systemd itself, the complexity causes issues with weird edge cases.
Early in my career I was all for systemd, thought it was the greatest thing ever, then I got bit by the edge cases a few too many times. Meanwhile I have had zero issues with openrc or s6.
I don’t buy the argument about all the auxiliary stuff. You are free to not use it.
