replying to both @SeventhSon and @Dnegreira
when there is an error in the handling of commands sent by lxc to lxd, lxc set the error code with the following strategy (lxc/main.go)
err = app.Execute()
if err != nil {
os.Exit(1)
so if there is an error, the lxc client returns 1 else 0
if the lxd server suffers a catastrophic problem such as a nasty admin sending it a SIGKILL signal, the end result is the same
Error: websocket: close 1006 (abnormal closure): unexpected EOF

lxc list | grep test1
