emOS v0.12-ea.1 (Early Access)
emOS now checks /data with its own e2fsck, and the Echo Dot 3rd gen gets Bluetooth. Early Access: only dev and EA controllers offer it; GA controllers do not see it.
The emOS update rewrites the Echo's boot partition. It checks the image before and after writing, and rolls back after three boots that never reach the controller; an Echo that fails before that point needs TWRP and a USB cable to recover.
Improved
- emOS carries its own e2fsck (e2fsprogs 1.47.4) and checks /data with it on every boot, on every Echo. The boot log names which checker ran (#1182).
- Bluetooth on the Echo Dot 3rd gen under emOS (#1134).
Fixed
- An Echo Dot 3rd gen never checked /data at boot: its FireOS has no ext4 checker, so /data was mounted unchecked. A controller from the next release refuses to build a Dot 3rd gen image without e2fsck; older controllers build images without it, as before (#1182).
Source
e2fsck is GPL-2.0: its unmodified upstream source (e2fsprogs-1.47.4.tar.gz) and licence (e2fsprogs-NOTICE) are published with this release, built by emos/tools/build-e2fsck.sh. busybox's are published as before.
