Good to know.

It depends. Tramp 2.1 has introduced a cache, which keeps information
about remote hosts persistently. This information enables Tramp to
access remote hosts faster.

In your case, the information about the test command has been changed,
which Tramp couldn't know. `tramp-cleanup-all-connections' is a good way
to flush the cache, in order to recompute all those information. It
shouldn't be necessary very often.

Additionally, Tramp flushes the cache on its own, when "uname -sr"
returns a changed result on the remote hosts.

All those measures should keep the cache consistent, as far as
possible. However, if you are in a situation, that remote hosts
configuration changes often, and Tramp does not notify, you might enable
the command in your .emacs.
