Start fakeroot daemon

$ faked-sysv --socket [/tmp/fakeroot.sock]

$ faked-sysv --debug

faked-sysv [options]

faked-sysv is the daemon component of fakeroot using System V IPC. It maintains a database of fake file ownerships and permissions, allowing unprivileged users to create archives with root-owned files.
The daemon intercepts file operations via LD_PRELOAD and returns fake ownership/permission information. This enables building packages with correct ownership without actual root privileges.
faked-sysv uses System V shared memory for communication, as opposed to faked-tcp which uses TCP sockets.

--socket PATH

Unix socket path for communication.

Enable debug output.

Run in foreground (don't daemonize).

Display help information.

Only fakes metadata, not actual permissions. Requires corresponding fakeroot wrapper. SysV IPC has system limits. Not security isolation.

faked-sysv is part of the fakeroot package created for Debian package building. It enables creating .deb packages with proper file ownership without requiring root privileges during the build process.
