More Details We make it easy for you to offer live support, which will improve your customer satisfaction ratings.Our real-time, built-in translator, breaks down language barriers by automatically detecting and translating chats into the language your customers use.Any client requests for daemons that are not yet running will be cached in the socket buffer, and then filled when the daemons are up and running.
Upstart has been the default in Ubuntu since 6.10 Edgy Eft and is available in most distros.
You can see these with $ netstat -a --protocol=unix Active UNIX domain sockets (only servers) Proto Ref Cnt Flags Type State I-Node Path unix 2 [ ACC ] STREAM LISTENING 4836 /var/run/dbus/system_bus_socket unix 9 [ ] DGRAM 4584 /dev/log unix 3 [ ] STREAM CONNECTED 489456 /tmp/orbit-carla/linc- aaa-0-476044c676da9 unix 3 [ ] STREAM CONNECTED 489455 unix 3 [ ] STREAM CONNECTED 489452 /tmp/orbit-carla/ linc-8ba-0-45fe9270a46b2 [...] As you can see the sockets have inodes, following the tradition of "everything in Unix is a file." So you can perform various operations on them with standard Linux file utilities, which is a fun topic for another day.
So all sockets for all daemons can be created in one step, and then all daemons in a second step.
Both have speeded up, but sysvinit is always going to be slow because it starts processes one at a time, performs dependency checks on each one, and waits for daemons to start so more daemons can start. There is a way to do this without all kinds of complexities, and that is to take advantage of the way Unix-type daemons work.
Clients of Unix daemons don't need to know if the daemons they depend on are actually running — all they need is the correct Unix domain sockets to be available. They are inter-process communication sockets (IPC), and they are how processes on the local system talk to each other.
