Subject: [PATCH] install-image-efi: STAGE configurable por entorno
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

El staging estaba clavado en work/.install-efi-stage. Cuando el rootfs fundido vive
en OTRO volumen —el store de este hub es un bind-mount de /dev/sdb y work/ está en
/dev/sdc— los hardlinks del staging fallan enteros con EXDEV, porque linkat() rechaza
cruzar MOUNTS distintos aunque sean el mismo fs. Con STAGE= se pone el staging del
lado correcto. Default idéntico al de antes.
