>Description:
Following along with https://www.netbsd.org/docs/rump/sptut.html specifically the Networking section I get the following:

laptop$ export RUMP_SERVER=unix://tmp/netsrv
laptop$ rump_server -lrumpnet -lrumpnet_net -lrumpnet_netinet -lrumpvfs -lrumpdev -lrumpdev_bpf -lrumpnet_virtif ${RUMP_SERVER}
[   1.0000000] pool redzone disabled for 'kmem-4096'
[   1.0000090] pool redzone disabled for 'buf64k'
rump_sp: failed to bind to URL unix://tmp/netsrv
rump server init failed: No such file or directory

>How-To-Repeat:
laptop$ export RUMP_SERVER=unix://tmp/netsrv
laptop$ rump_server -lrumpnet -lrumpnet_net -lrumpnet_netinet -lrumpvfs -lrumpdev -lrumpdev_bpf -lrumpnet_virtif ${RUMP_SERVER}
[   1.0000000] pool redzone disabled for 'kmem-4096'
[   1.0000090] pool redzone disabled for 'buf64k'
rump_sp: failed to bind to URL unix://tmp/netsrv

 It works with RUMP_SERVER=unix:netsrv
 (just noting)

 I was not trying to say it is not a bug - /tmp/netsrv sounds like a valid
 unix domain socket path to me.
