Re: [Libguestfs] [PATCH nbdkit 06/10] server: Make --run imply -U -

Almost always when you used nbdkit --run you should also use -U - (to use a private Unix domain socket). Otherwise nbdkit listened on TCP port 10809, which had two bad side effects: It permitted other processes to interfere with your --run command, and it reserved a public TCP port which would stop two instances of nbdkit running at the same time. This was a frequent cause of bugs in test cases.

Switch the default so now --run implies -U - You can still get the old behaviour by using --port explicitly, but that is almost certainly a bad idea. (Using --run and --vsock works the same way as before too. It is also usually a bad idea, although we use it in one test.) --- docs/nbdkit-captive.pod | 7 ------- docs/nbdkit.pod | 9 ++++++++- server/main.c | 9 +++++++++ 3 files changed, 17 insertions(+), 8 deletions(-)
