# GitHub-hosted runners keep most of their free space on /mnt (~66G),
# while / has far less headroom. Building the image and then re-layering
# it with Chunkah keeps two copies of the root filesystem in podman's
# storage at once, which can exhaust /. Relocate podman's rootless
# storage onto /mnt so the rechunk has room. The image-copy temp dir is
# deliberately left on / (freed by relocating storage) so the two large
# consumers land on separate disks instead of competing for one.
