One issue is that we've got multiple protocols mixed up in here. So, for
instance, the fingerprint only applies to SSL (and not SSH!) and
remotecmd only applies to SSH. Also, you might possibly have different
usernames for http/ssh on the same host. The [auth] section deals with
this with the schemes marker, which lets you have a foo that applies
only to ssh and a bar that applies only to https. But that's rather
suboptimal. It might be better to have:
foo.username = alice
foo.username.ssh = aliceb
Also, Mads' trick can be applied here:
foo.val = x
is the same as:
val = x
Mathematics is the supreme nostalgia of our time.
