Testers wanted: Squashfs

make sure you read and understand what we expect from testers
So what now?
Goal: make recalbox like a firmware, make updates much faster, make recalbox more robust
Archs: Pi3 only for now. x86_64 should come shortly
A squashfs file is like a read only image file that can be mounted like any device. Part of it is in memory.
Steps to update and test - Pi3 only for now
- Update to the mentionned branch (i mean do update, not juste change the update type)
- Once the update is done:
mount -o remount, rw /boot echo "boot=squashfs" >> /boot/recalbox-boot.conf /recalbox/scripts/upgrade/recalbox-upgrade.sh upgrade && reboot
From here, Recalbox will download a squashfs, copy it on first reboot with the usual upgrade progress bar, and transparently finish the update on the following reboot.
To make sure everything happened as expected :
dmesg | grep irfsshould be quite self explanatory
mount | grep overlayshould return a single line
Expected test cases
There are many cases that need to be tested, here are a few independant scenarios :
- your Recalbox still boots with NOOBS
- you have a USB key/hard drive
- you upgraded from a 4.0.x version to 4.1 (or later)
- you installed Recalbox with the .img
Please report your environment as I need to make sure all cases are covered, and mostly that the update doesn't break anything.
@substring Ok so here is my result.
- Starting from 17.11.02 stable. Download of update from branch: OK
- Auto upgrade after reboot: OK
- recalbox-boot.conf trick and command-line download of update: OK
- Auto upgrade after reboot with "upgrading the squashfs" message: OK
- Final reboot: OK, Recalbox works as expected.

Out of curiosity: Does this squashfs feature will work somehow like a switch firmware in the future, having 2 "base images" and booting the newest one or the backup if the user wants to change it? Example:
SWDEP_02# show bootvar Image Filename Version Date Status ----- --------- --------- --------------------- ----------- 1 image-1 220.127.116.11 09-Mar-2017 13:23:09 Active* 2 image-2 18.104.22.168 01-Sep-2010 15:26:19 Not active "*" designates that the image was selected for the next boot
