Re: [Libguestfs] libguestfs supermin error



Hi Rich

I'm able to solve this.
I copied uImage to vmlinuz-3.8.13-rt9-QorIQ-SDK-V1.4 and I'm now able to proceed.

Thanks a lot for the help despite being on vocations.:-)

If you follow the code in src/kernel.ml you'll see that this means
supermin was unable to get the kernel version from the supplied kernel
file.  The code is fairly simple to follow.  I barely have internet
access here and in any case I don't know what's in that uImage file,
so I suggest compiling supermin yourself, running the command by hand,
and adding printf's to src/kernel.ml in supermin to find the problem.
