Flatpak, docker, and nix cover a lot of things but have their annoying edge cases and paper cuts, especially in comparison to snap in some ways for some apps.
I’m still pretty new to nix - I’ve only recently started experimenting within a NixOS-loaded VM. So, please pardon me for my ignorance. But would you be so kind to point me towards its “annoying edge cases and paper cuts especially in comparison to snap in some ways for some apps”? Thank you in advance :) !
Syncthing helps with syncing the bash script across all of your devices. However, as for restarting itself after the update/change, you might want to setup a daemon/service (or something) that restarts the bash script whenever Syncthing does its bidding.
