Installer should wait for network connectivity #3
Description
If the installer runs before network connectivity is established, the pacstrap boostrap will fail with a misleading error about pacman mirrors.
The solution is simple: make the installer aware of network connectivity!
A simple MVP would be for the installer to check the outside world and exit gracefully if there's no connection.
A proper solution would be to check and sleep the install process for up to a minute until connectivity is established.
