Hi Mischa, all,

sorry, couldn't make it earlier.

I assume this is what Mattias spoke about earlier in [1]:
```

The gsi patch is these package are smaller than the one in GT upstream,
because part of the changes needed have already been made by the
existing Fedora openssh patches. The gsi patch itself doesn't change
much, but it did need some updates for the openssl 1.1 migration that I
ported from the changes made to the patch in the GT repo.
[...]
```
...,right? I hence assume such a patch is already available from Mattias 
then.

So users could use plain `ssh` with GSI proxy credentials instead of SSH 
keys with these extra modules? Interesting, where can we get more 
information about these modules? And will this also support delegation?

Cheers,
Frank
