Offline installation, more MT7921K fixes, larger size with larger fun. For system updates, check https://t.me/HoloISO

Visible changelogs:

• Add a small chroot applet in order to open terminal in existing installation for fixing some stuff
  

• Option to reuse existing home partition
  
  

• Get rid of NVIDIA drivers, sorry but i had to.

• Fully autonomous installation of specific shipped version!
  
  

• Device specific stuff being added for Anbernic Win600 and Steam Deck, one being a gamepad driver, and other being it's own linux firmware for latter
  

• More work on MT7921K/RZ608 compatibility (Applies to OS image updates too)

OS installation changelogs:

• Track power button events in gamescope (cool cute deck sleeping anim)
• Instead of checking updates on OOBE, make sure we do a FULL first experience update, which will guaranteedly push us to "Sign in" menu after OOBE
• Fix 1440p/1600p displays breaking themselves, by reverting Valve's external display policy
• Fix broken mouse pointer behavior on gamescope for Intel iGPUs
• Add OneXPlayer Mini Pro as localized-rotation device in gamescope and desktop environment
• Offload user-writable system directories (such as, flatpak, logs and etc.) under /home/.steamos
• Disable package signature checks (Valve somehow broke keyrings, and current Arch derivation is considerably old)
• Refactor session switching logic, by entirely reimplementing the "sentinel" based configs to not invoke any regular expressions on sanity file itself
• Split "firstboot-config" from using desktop orientation in order to make sure rotation always works including offline installation images
• Ship more fonts, including ttf-dejavu, emoji
• Ship more packages such as pavucontrol, KDE Partition manager, gamemode, cpupower, bluez-plugins/bluez-utils
• Stop making reboot/shutdown rely on specific tracker to reduce CPU usage and make shutdowns more safe for Steam Client
• Workaround flatpak mirrors to instantize flathub-beta repository as well as backend for it
• Update autologin.conf file with teardown as well as Relogin fixes in order to reduce session selection time by a good amount
• By including a refactored session switching logic, "steamos-session select plasma-x11-persistent" will always work no matter where you start to invoke it, this is gonna be useful for botched GPU users/additional maintainence stuff
• Allow logind to kill user processes after sessions are being switched, reducing entire switching time from 10-15s to a mere 7-8 (Measured on Anbernic Win600 with M2 SATA SSD)
• Invoke desktop mode as "oneshot" trigger ALWAYS in order to not hit any teardowns for GPU as well as framebuffer
• Make rotation work only on main display, as this made external monitors go funni on some devices
• Disable color compression on Intel GPUs to silence some glitches
• Forcefully install holo-wireplumber to make HDMI audio outputs not kill themselves because they wanted so
• MESA/Vulkan: Update to 22.1.7 with specific Vulkan backports for Intel systems, in order to correctly use gamescope
