#22441: rootfs mounted as read-only
-------------------------+---------------------------------------
Reporter: chatoooo@… | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone: Designated Driver (Trunk)
Component: base system | Version: Trunk
Keywords: |
-------------------------+---------------------------------------
I build the latest master branch commit
cda52dcb329e02674175b60426be26cd813294a6 for RPi3. After flashing this
build device was not accessible over the network. So I connected serial
cable and noticed that rootfs is mounted as read-only. System does not try
to remount rootfs as RW.

So I tried to build the version that worked for me. It is commit
