True, but here that allows you to talk to the machines actually listed
in ‘deploy.scm’. Were you to use an external tool, you’d have to
somehow grep/sed the thing to get a list of host names.

Yes, and it would use the same mechanism. It would also more pleasant
for things you want to routinely do after a deployment.
Still, sometimes you just want to run “uname -a” or something to see if
you rebooted the machines, and a deploy hook won’t help with it.
WDYT?
Thanks,
Ludo’.
