suspend module is part of go-luks-suspend so obviously you can't use it after package removal.

I think his point is that the hook should be removed in the post-uninstall scripts, no?

[Maryse47]

As long as there is post-install script that adds this hook, yes. But there is no such script. Adding the hook is manual process done by user therefore removing hook manually is logical and consistent step. keep in mind that manipulating mkinitcpio.conf automatically would be error prone with risk of locking out user from system on next boot. No tool in Arch does this.

Indeed, it's sensible that it's this way then. Thanks for the explanation.
