Dear List,

I try to build Poky and the final rootfs image doesn't not mount with the
following problem:

----------------------8<-------------------------8<------------------------------
BIFS: mounted UBI device 0, volume 0, name "polatisnic-rootfs"
UBIFS: mounted read-only
UBIFS: file system size:   10737408 bytes (10485 KiB, 10 MiB, 82 LEBs)
UBIFS: journal size:       1964160 bytes (1918 KiB, 1 MiB, 15 LEBs)
UBIFS: media format:       w4/r0 (latest is w4/r0)
UBIFS: default compressor: lzo
UBIFS: reserved for root:  0 bytes (0 KiB)
VFS: Mounted root (ubifs filesystem) readonly on device 0:14.
devtmpfs: mounted
Freeing init memory: 208K
INIT: version 2.88 booting
mount: permission denied (are you root?)
mount: permission denied (are you root?)
grep: /proc/filesystems: No such file or directory
mount: permission denied (are you root?)
grep: /proc/mounts: No such file or directory
grep: /proc/mounts: No such file or directory
Remounting root file system...
mount: can't read '/etc/mtab': No such file or directory
------------------------8<-----------------------------------8<------------------

After a bit of research, I fount out that the busybox was populated in the
rootfs
under ownership of "andreas:andreas" instead of "root:root"

I fixed manually the ownership and it booted  up.

Does anyone knows what might be going wrong in my build process?

Any guidance would be very helpful.

TIA
Andreas

Once again, with enthusiasm, you'll need to explain your complete build process for
anyone to be able to help you.
   * What's your build host
   * What version of Poky/Yocto are you using
   * What is your target MACHINE
   * What, if anything, have you added to local.conf

Without this kind of information, answers would be only guesses...
