+Subject: [PATCH] input/ssh.ml: Add debugging around remote_file_exists
+ function
+
+It's hard to tell when this function was called and if it returned
+success or failure, so add some debugging.

+Subject: [PATCH] input/ssh.ml: Fix Ssh.remote_file_exists
+
+This function was inadvertently broken in commit 970d7123c2
+("input/ssh: Use nbdinfo --can connect (instead of --size)"), since
+'nbdinfo --can connect' just says that nbdinfo managed to connect at
+all, even if the connection failed to fully negotiate the NBD
+handshake.  (This is possibly a bug in nbdinfo.)
+
+Using --size means we must have negotiated the NBD handshake.
+
+However this leaves the problem that commit 970d7123c2 was originally
+intended to fix, that 'nbdinfo --size' prints the size on stdout.  To
+fix this, replace use of run_command with shell_command so we can
+redirect stdout.
