1. Don't overwrite the dropbear package for this. Just create a new package
with the 'files' template to install your file.
2. You need to explicitly create /root in your package (or dropbear if you
want to stick with that) with the same permissions as the rootfs
package. And you should probably create /root/.ssh with the correct
permissions as well:
@$(call install_copy, dropbear, 0, 0, 0700, /root)
@$(call install_copy, dropbear, 0, 0, 0700, /root/.ssh)
@$(call install_alternative, dropbear, 0, 0, 0600, \
/root/.ssh/authorized_keys, n)
Note, there is a bug in the latest ptxdist release. I think this will still
fail, so you need to copy scripts/lib/ptxd_lib_check_dir_permissions.awk
from ptxdist master into your BSP.
