The service interface

The program psxrun.exe is a Win32 application that mediates POSIX processes that must access the Windows Service Control Manager. Interix subsystem services can be administered with the Services administration utility in Control Panel, or with the Interix service(1) utility.

You can use the service utility to install, start, and stop a service. Because Windows associates a user account with a service, you can supply a user name and password when the service is installed. If no user name is provided, it defaults to the user LocalSystem, which is equivalent to logging on as an administrator, but without network access.

When you use either the Windows Services utility or the Interix service utility to terminate a service, the program psxrun.exe sends a SIGTERM signal to the service. Although some daemons use signals for interprocess communication, SIGTERM is unlikely to interfere with those daemons.
