Hi Siebren,

Try adding something like this to your recipe:

python populate_packages_append () {
         # Non-empty directory permissions don't get preserved by the
         # normal populate process.
         def dirperm_hack(d):
                 pkgdest = bb.data.getVar('PKGDEST', d, 1)
                 pn = bb.data.getVar('PN', d, 1)
                 os.chmod(os.path.join(pkgdest, pn, '/home/root/.ssh'), 
0700)

         dirperm_hack(d)
}

I made a failed attempt at fixing this in package_deb.bbclass, but it 
caused other problems; in the end I figured it was easier to work around 
it in the one recipe where I needed a non-empty directory with 0700 perms.
