[poky] do_rootfs() RPM error message

[Rob Woolley]

Hi,

I ran into a minor build system glitch and wanted to share the
workaround I used.

I was following the steps in the Poky quick start guide.  When the
build got to the do_rootfs() task, the rpm command complained on all
packages with:

 	installing package <PKG> needs 125MB on the /boot filesystem

My /boot partition is only 100MB which is what triggered the problem.

However, since the disk space on the host filesystem is irrelevant for
assembling the rootfs for the target, I added --ignoresize to the rpm
line that triggered the problem.

I suspect that it's related to the fact that rpm -U was used with
--justdb and without --root.  It may be needed on similar rpm calls as
well.

Once I made the change my build completed successfully.

Cheers,
Rob
