So regarding libssh... what I discovered is that libssh deprecates the
DSA key algorithm (it is of dubious strenth, after all), and 0.10.x
disables DSA by default. Passing -DWITH_DSA=on to re-enable DSA support
in the libssh build helps guile-ssh pass most tests, but some tests
still fail. Since libssh plans to entirely remove DSA support in future
versions, may as well adapt sooner than later...

For Debian at the moment, I've patched out the DSA code from the
guile-ssh test suites, and that seems to work fine.

Clearly this has been a blocker for me... I don't have any systems where
I use that functionality, and I haven't taken the time to set them up to
test myself.

Anyone willing to offer some "guix copy" testing to have greater
confidence in updating guile-ssh? :)

So, here we are... :)
