This is a big change, yes. Dump unix sockets in the same manner as all the other files are done now. A few notes however. 1. We explicitly drop names for connected stream sockets. This is done to avoid conflicts with names -- accepted sockets share their names with the listening parent. This can be done later by binding a socket to a name, them renaming it to some temporary uniq one and at the very very end renaming some back to original. 2. Interconnected sockets are restored via socketpair() call. This is correct, but names are dropped. Need to bind() sockets after this (yes, this can be done), but for this we need to implement the trick with renames described before. 3. FD for socket queues is constantly re-opened not to resolve fd conflicts. Need to use service fds engine for this later. 4. Some code cleanup is still required, yes (will follow shortly).
