[Haskell-cafe] Status of ghcup?

[Mario J. Hesles]

Hi Todd,

Perhaps you could set everything up once on a server, create accounts for
each of your students, and then just have them ssh into it and do their
work remotely? It's not ideal, but it would be better than wasting so much
time debugging boring install issues. The adventurous ones can try
installing everything themselves.

Sincerely,
Mario J. Hesles
