gstfsd mounted every partition it listed: a root on LVM was never found, a disk with two OS roots got the change twice and two concatenated replies, and no root, an error or a request longer than 1024 bytes ended the connection without a reply. It now lets libguestfs inspect the guest, mounts its one OS the way the guest does (a broken filesystem off the changed path is left out), and sends exactly one reply, keeping the first error. The root entry is found on any line of /etc/shadow and must be unique; a key needs no shadow file. A request is at most 64 KiB. Each change runs in a worker process with a directly started appliance; both are killed when the request is not done 100 s after gstfsd accepted it (GSTFSD_DEADLINE may only lower that), before the panel's 120 s timeout releases the VM, or when the panel's connection ends, and the reply waits until they are gone, so nothing touches the disk once the panel has given up. A worker that dies says why. The panel connects over IPv4 or IPv6, sends the whole request and reads the reply until gstfsd closes.
