Subject: [PATCH] block: make extroot mount preparation more robust
The extroot mount preparation code for r/w rootfs overlay discov
I had trouble using an ext4 extroot overlay on my Zyxel NBG6817 running
18.06.2, so I took a closer look at the way libfstools and its block
tool setup the extroot overlay during PREINIT and found some things
broke extroot mounting on certain devices.
The issue and logs are documented in the follo
