Migrate GNOME default config overrides into simple system-wide configs

[xalt7x]

Currently GNOME edition stores dconf database in /etc/skel/.config/dconf/user file which eventually copies into $HOME/.config/dconf/user

Database content can't be opened with a simple text editor. User needs to dump it first. GNOME 3.x provides a better mechanism for administrators. One can customize GDM/login settings and session/user settings.

Files are easily readable, override default settings and survive system upgrades better.

Examples:

1. Enable "tap-to-click" touchpad setting on GDM login screen

/etc/dconf/profile/gdm

user-db:user
system-db:gdm
file-db:/usr/share/gdm/greeter-dconf-defaults

/etc/dconf/db/gdm.d/01-custom

[org/gnome/desktop/peripherals/touchpad]
tap-to-click=true

---

2. Enable "tap-to-click" touchpad setting for a user session

/etc/dconf/profile/user

user-db:user
system-db:local

/etc/dconf/db/local.d/01-custom

[org/gnome/desktop/peripherals/touchpad]
tap-to-click=true

Thanks for the excellent suggestion. Due to the very large number of customizations to dconf across all the different SpiralLinux editions it's not really practical to implement all the overrides in this way. Basically to create the configuration I load up the SpiralLinux system in a VM and configure the desktop visually and then copy the ~/.config/dconf/user file to the ISO live build /etc/skel/ directory. However there are a few settings that aren't practical to implement that way, and I have set them as you suggest in https://github.com/SpiralLinux/SpiralLinux-project/releases/tag/12.231001
