/etc/fw_env.config deleted after migration from 3.11.26 to TOS 5.1.4
If you use foris experimental update from 3.11.26 to TOS 5.1.4 the file /etc/fw_env.config get's deleted so you can no longer use fw_setenv to switch from ssd to emmc and vice versa.
I don't know if it is possible to deploy a proper /etc/fw_env.config for the different Hardware out there but I think at least if should not be deleted. It can be cumbersome to search the forums for a proper one if you for example want to be able to switch from 3.11.26 (msata) to 5.1.4 (emmc) and vice versa.
