Hello Randy,

I got the following message:
 "file system is read-only" 

if I try to touch a file that is not on /tmp, or when I start a systemd
service that tries to write on the file system.

After some research, I go it fixed by changing to read/write on the
script that was with read only.

I thought this would be useful for someone else.

Reading the patch you sent me, Darren says that a proper fstab will ensure
the rootfs is rw. 
Maybe I'm missing this. I will look for this to make sure that my fstab OK.

Thanks
