Hi All,

After updating Buildroot (commit
da9eff07fda36a1f4703a6232051da86c2d91d1f), I observed that my ubifs/ubi
root filesystems were approximately 200MB larger.  I noticed the
following build output:

    :
    :

Due to a circular dependency, it appears that rootfs.ubifs is generated
before the target directory is finalized.  I think this might explain
the increased size. 

I've never noticed the 'Circular ... dependency dropped.' output before
my latest pull.  Doing a little digging, I found the following:

    fs: add rootfs dependencies to PACKAGES
    
    The logic for creating most of the filesystem images requires a
    certain number of host packages to be built. However, those packages
    are not currently listed in the global PACKAGES variables, and they
    are not dependencies of any other package listed in the PACKAGES
    variable.
    
    While it does not have any practical implications, it makes sense to
    have those packages listed in the global PACKAGES variable, which this
    commit implements.

My ubifs/ubi root filesystems returned to their, approximate, expected
sizes after reverting commit 4570dbc.

Has anyone else observed this behavior?

Do I have something mis-configured?

Thanks and Regards,
