If RAM is lower than 2GB, Install should suggest to create a swap space to avoid kill of crystal compiler

[GauthierPLM]

Is your feature request related to a problem? Please describe.
If not enough RAM is available, Crystal compiler will be killed by the system when building Invidious.
The script already have an option to add swap space. A check at the beginning of the install process should warn the user that, if their machine have less than 2GB of RAM, adding a swap space is recommended.

The option could even be part of the install process and would call the swap creation on demand.

Describe alternatives you've considered
Currently, if the crystal compiler is killed, no message warn the user that not enough memory is available.
Therefore, the user should be aware of the issue and creating the swap space before doing the install.

This might confuse new comers or people not aware of the required RAM to build the project.
