$ abra -d app move foo.bar server.two
(many lines)
INFO <app/move.go:141> moving volume foo_bar_content from server.one to server.two
DEBU <app/move.go:147> creating volume foo_bar_content on server.two
DEBU <app/move.go:157> creating foo_bar_content_outgoing.tar.gz on server.one
(hangs for a long time even with a few kB of data in the volume)

I suspect this is because sudo requires a password on server.one.

If this is an unavoidable limitation, maybe let's document in the -h output?

Hmmmmm yes, that does like sound like a sudo interactive prompt hang? It is documented but is there actually instead a way to test this up front and bail out? I'm not sure. More CAPSLOCK in the sub-command docs and/or a warning output when running the command? I'm open to whatever people feel is proportional 😛

It is documented

If passwordless sudo is required (and it seems to be) then I would humbly say that should be added to the -h output, I have '"sudo" permissions' (from the existing -h) on both servers… but not passwordless.
