I had someone walk up to me and ask me how you make the powershell snap their shell. Is there a way to add an entry to /etc/shells when the snap is installed?
There’s no specific support in snapd to manage the
With that said, as a classic confinement snap there is nothing preventing hooks from modifying files on the base system. A
configure hook that ensured your shell was listed in the file, and a
remove hook that undid that would probably do the trick.
debianutils package contains
remove-shell scripts that could help with this. You can’t rely on them being available on non-Debian derived distros, but you could stage them into your own snap.
I tried using the
SNAP variable to calculate the path, but at runtime the path is different than when the hook ran. I guess I could substitute current. Also, I would prefer to use
/snap/bin/<name> but not sure if the path varies on different distros.
