 ## Problems found in the Steamify ISO (fix in `steammachine-cachyos-live-iso`, PRs into `feat/steamify`)
+- Fixed (PR #2): cachyos-installer's `bootctl install` runs in a chroot and writes no EFI boot entry, so systemd-boot

+  `steamify-install` now registers it with efibootmgr from the live system.
+- `/var/log` (`@log`) isn't mounted when `steamify-install` runs: its logs are hidden under the mount after boot.
 - cachyos-installer leaves systemd-boot with `#timeout 3` and no default entry: a real machine waits in the menu for ever
   (the test setup papers over it in `share/vminstall-post.sh`).
 - It enables ufw, which drops ssh from the host (the test setup runs `ufw allow 22/tcp`).
