commit e0cbf8ae204ad2d4d411d579e350a61f0a79048d Author: Philip Peterson <1326208+philip-peterson@users.noreply.github.com> Date: Tue Oct 6 05:25:05 2026 -0800 Initial commit: Layer Wizard A GUI installer wizard for permanent rpm-ostree package layers on bootc/image-based systems. Walks through: welcome/current-version check, package name entry with existence check, confirmation, then a streamed rpm-ostree install via pkexec. On success, writes a pending-confirmation marker and installs an autostart entry so the next login shows a "did this update work?" screen with a one-click rollback (bootc rollback --apply) if not.
