The image's fstab keeps the factory slots mounted under /factory, and
busybox mount's auto-type iteration against an already-mounted ext4
device provokes a cosmetic kernel 'Can't open blockdev' for each
foreign-type claim (reproduced and pinned on the bench: ext3-typed
mount of an ext4-held device prints it; ext4-typed does not). Probes
now reuse an existing mountpoint from /proc/mounts and mount fresh
targets with an explicit -t ext4.
-l inventories every bootable partition (SD, eMMC slots 1/2, legacy
p4) as machine-parsable key=value lines: firmware type
(forgefirm/factory), version, kernel presence, booted/next markers,
plus the saved-env selection - the shared probe for the installer and
the forgectrl update manager.
Boot switching now writes all four selection variables (mmcdev,
mmchwpart, mmcpart, mmcroot) in one fw_setenv -s transaction and
read-back verifies, falling back from the libubootenv script format
to the classic u-boot-tools format to per-variable writes - the same
script works on factory firmware and ForgeFIRM. mmchwpart was
previously never set and a mixed env could survive a mid-flip power
cut. Switch targets must pass a content probe (rootfs mounts, kernel
present) unless -f. -e picks the newest factory slot by probing,
excluding slots occupied by ForgeFIRM.
The new ffboot recipe installs it as /usr/sbin/ffboot with
/etc/fw_env.config (factory-identical redundant env layout at eMMC
0x80000/0x82000) - previously the image shipped fw_setenv with no
config. Added to forgefirm-image.
install-forgefirm.sh completed silently broken when the download, flash
write, mount or uEnv rewrite failed - add die() checks around every
critical step (audit N13/M12) and download the release asset under the
exact Scarthgap artifact name (forgefirm-image-glowforge.rootfs.wic.gz)
so uploads need no renaming. ffboot no longer depends on the never-
provisioned /etc/fw_env_mmcblk2.config: it falls back to
/etc/fw_env.config (which both the factory and ForgeFIRM images ship,
pointing at the eMMC env) and checks fw_setenv results (audit N16).
BUILD.md gets the real artifact name and marks the built u-boot
reference-only; INSTALL.md drops the stale script/ogboot names and the
cloud-connect promise, stating the image is bring-up-only (audit N11).
