Overlays

Two directories under iso-profiles/antergos/ control what goes into the ISO.

iso-profiles/antergos/
├── profile.yaml
├── root-overlay/     # → rootfs (squashfs)
└── live-overlay/     # → live environment (initramfs)

How overlays work

root-overlay/ files are merged into the root squashfs — they become part of the installed system
live-overlay/ files are copied into the live environment only — they’re not present after installation
Overlays are self-contained (no symlinks to external directories) so the repo builds standalone
Live-overlay files are copied via cp -LR in make_livefs(), not overlay-mounted. Deleting a file from live-overlay exposes the package version underneath

Disclaimer: No symlinks were harmed in the making of this ISO. Well, maybe a few. We killed some.

Also: this ISO is 100% systemd-free. Not even a trace. We checked. Twice.
