webpack > 5 does not ship polyfills anymore

Creating a current (i.e. ^5.0.0) CRA will result in missing polyfills.

That will make a typescript project fail to compile.

A workaround is to provide the polyfills with craco. Find the neccessary configuration snippets in the files below.

Why to use an offloader for freifunk

• The er-x has more computing power than cheap WiFi router and can act as a VPN tunnel gateway for multiple nodes.
• It is possible to connect several APs (in my case unifi AC lite) to the LAN ports of the er-x to increase coverage

Make a single ssh-key work as well for ssh-logins as for access to gitlab-repositories

Imagine you have a server, that does not allow you to create a dedicated user for gitlab (e.g. uberspace). That puts you in the situation that you would need different ssh-keys to either access gitlab or the shell.

gitlab-shell redirection

Gitlab uses the command option in authorized_keys to limit access for the owner of the private key to only gitlab-shell. This in fact disables regular shell-access for that very key.

Add a switch
