 # PS5 Linux Image Builder

+Builds bootable Linux USB images for PlayStation 5 using Docker containers. Supports Ubuntu 26.04, Arch, CachyOS (Gamescope + Steam), and full Kali Linux, individually or as a multi-distro image with kexec switching.

 ## Prerequisites

 - Docker (with permission to run `--privileged` containers) — install as per your distro's instructions
- ~30GB free disk space
+- ~30GB free disk space for Ubuntu, Arch, or CachyOS; a full Kali build needs
+  substantial working space because it creates a 96GB image and a full rootfs
+  tree (`~150GB` free recommended for a clean Kali build)

 Once Docker is installed, add your user to the docker group and apply it without logging out:

+## Kali First Boot Time Sync
+
+The Kali image uses UTC by default and enables `ntpsec`. PS5 hardware may boot
+Linux without a correct real-time clock, so the displayed time can be wrong
+until a network connection is available. The Kali recipe configures IPv4 NTP
+sources that were validated through Android USB tethering, because that
+connection may not provide usable IPv6 routing.
+
+The Xfce clock's **Time and Date** window is the legacy `time-admin` utility.
+On Kali it can report that NTP support is not installed even though `ntpsec`
+is installed and active. Verify or repair synchronization from a terminal:
+
+```bash
+systemctl --no-pager status ntpsec
+ntpq -pn
+timedatectl status
+```
+
+If the PS5 clock is still wrong after the internet connection is active, force
+one initial correction and restart continuous synchronization:
+
+```bash
+sudo systemctl stop ntpsec
+sudo ntpd -gq -c /etc/ntpsec/ntp.conf
+sudo systemctl start ntpsec
+date
+```
+
+To use a local timezone after boot, for example Kentucky:
+
+```bash
+sudo timedatectl set-timezone America/Kentucky/Louisville
+timedatectl status
+```
+
+The Kali desktop autologin is enabled for local first boot. SSH is installed
+but disabled by default because the initial local account is `kali` with
+password `kali`. Before enabling remote access, change that password:
+
+```bash
+passwd
+sudo systemctl enable --now ssh
+```
+
+The image holds its installed kernel packages and protects the boot-copy hook
+from deploying a generic Kali kernel. Do not replace or unhold the PS5 kernel
+unless you are intentionally testing a new PS5-patched kernel build.
+
+Ghidra is configured to use JDK 21, its documented supported runtime. Full
+Kali installations may also contain newer Java versions for other software.
+
+`kali-linux-everything` installs NFS client components, but the PS5-patched
+kernel has NFS disabled. A failed `run-rpc_pipefs.mount` unit can therefore be
+reported at boot; it only indicates that NFS mounts are unavailable. The Kali
+desktop and security tools are unaffected.
+
+The full Kali toolset also enables `chkrootkit.timer`; its daily integrity scan
+can use noticeable CPU time while it runs.
