faked-sysv

System V IPC-based fakeroot daemon

TLDR

Start fakeroot daemon

$ faked-sysv

Run with specific socket

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

Debug mode

$ faked-sysv --debug

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.

PARAMETERS

--socket PATH

Unix socket path for communication.

--debug

Enable debug output.

--foreground

Run in foreground (don't daemonize).

--help

Display help information.

INSTALL

sudo apt install fakeroot

sudo dnf install fakeroot

sudo pacman -S fakeroot

sudo zypper install fakeroot

brew install fakeroot

nix profile install nixpkgs#fakeroot

CAVEATS

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

HISTORY

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.
