- Now uses `sh`-style single-bracket `[]` POSIX syntax instead of the truly old-school `test` syntax. Both are equivalent and equally portable. In fact, `man test` explains everything that `[]` can do.
- We now symlink the user's autostart file to the uBlue image's own file, and we do it in a backwards-compatible way which replaces the user's current legacy script file (if any). The previous system dumped a permanent file in the user's home-directory which never updated again after that, which meant that OS updates could never fix or improve the autostart scripts in the future. That's now possible, thanks to being a symlink.
- If the user uninstalls uBlue, or switches to a flavor without `yafti`, then the leftover "autostart" symlink will simply be a minor nuisance that only causes some soft, invisible syslog warnings about the "broken symlink", which is an improvement over the previous system which kept a full `.desktop` file that attempted to run a binary and failed to find it.
Notable changes:
- The icon is no longer dependent on "GNOME Terminal" being installed. Will now work on any desktop environment, not just GNOME. We only see this icon in "GNOME Tweaks: Startup Applications" or similar autostart-managers, which is even better reason to use a generic, always-existing icon for the shortcut.
- Now runs the new "autostart.sh" yafti GUI launcher.
- Tells the OS to not spawn a terminal window when running this shell script.
Instead of having to use a restrictive command-line in a ".desktop" file, we are now able to use scripting to create more advanced launchers, or if someone wants to easily switch yafti to something else.
* feat: add nix install script from bluefin / dnkmmr
* feat: add nix-me-up just cmd from bluefin
* feat: just update nix if installed
* feat: add nix-app-icons.sh
enables desktop icon support by adding to XDG_DATA_DIRS
* chore: remove nix update for now
this will be added in a later PR
