When I'm trying to install mono, this happens:

```plaintext
$ guix install mono
The following package will be installed:
   mono 6.12.0.206

substitute: updating substitutes from 'https://ci.guix.gnu.org'... 100.0%

```

So when trying to build mono 6.12.0.206 it want's to build all those 
other versions first. Is this due to how mono is designed, or do we have 
an issue with dependencies in guix?

Mono isn't small, it takes a while to compile, so this takes up quite 
some resources.

There doesn't seem to be substitutes for those packages yet, so I'm 
going to wait before installing those. Otherwise this will compile on my 
system for a few hours I'm afraid.

Cheers

It’s not an issue, but rather a solution to ensure everything is built
from source:

  https://guix.gnu.org/en/blog/2024/adding-a-fully-bootstrapped-mono/

Though of course, building it all from source takes a while…

HTH!
