Hi Lionel,
Yes, I have a modified kernel (2.6.32.14) config file that I have been
using from my beginning with buildroot starting with the 2010.05 and
08 releases. I basically am using that config file and then answering
N to all the deltas when buildroot/linux kernel detects the
differences in the config file between the releases and prompts me
before the kernel build. I am configuring for NFSv3 in the kernel but
am not asking buildroot to build nfs-utils at this time if you think
that might make a difference here. Although, I am hard pressed to see
where NFS comes in as it's not even being started at bootup time. I
didn't see anything in my kernel config building about setting up a
read-only filesystem. Are you thinking something is buried in my
kernel config?
Maybe, but I am running on buildroot 08 without this problem.
Although, I am building all my app packages under that one and maybe
something is overriding it and masking the original problem???
