[yocto] unbootable image produced with PACKAGE_CLASSES ?= "package_ipk", /etc missing

Thu Nov 28 23:28:28 PST 2013

Hi Todd,

I can reproduce the similar problem now, I think that it should be a
bug of e2fsprogs, it seems the debugfs can't know the free space
correctly, and thus it appears no free blocks, I'm sorry to say that
I can't fix it in a short while, but I will fix it in one or two weeks,
maybe you can set this in the local.conf as a workaround:

IMAGE_ROOTFS_EXTRA_SPACE = "51200"

If 51200 is not enough, it can be higher, the unit is Kbytes.

And the todd-new-wandboard-dual.tar.bz2 works well is because it doesn't
generated by debugfs.
