I also thought that perhaps it was a umask issue, but as you can see below,
umask is 0022, which should be ok.
The permission problem that I am having on the target is that
systemd-networkd.service won't start because it can't read the
configuration files below. These files are installed in systemd.make via:
ifdef PTXCONF_SYSTEMD_NETWORK
@$(call install_tree, systemd, 0, 0, -, /usr/lib/systemd/network)
@$(call install_alternative_tree, systemd, 0, 0,
/usr/lib/systemd/network)
endif
@$(call install_alternative, systemd, 0, 0, 0644, \
/usr/lib/systemd/network/99-default.link)
The install_tree code resolves the permissions to apply to the files
installed in ptxd_install_generic() found in
scripts/lib/ptxd_make_xpkg_pkg.sh by obtaining the file's permissions via
stat -c:
stat=( $(stat -c "%u:%g:%a:0x%t:0x%T:%F" "${file}") ) &&
IFS="${orig_IFS}"
local usr="${usr:-${stat[0]}}" &&
local grp="${grp:-${stat[1]}}" &&
local mod="${stat[2]}" &&
local major="${stat[3]}" &&
local minor="${stat[4]}" &&
local type="${stat[5]}" &&
case "${type}" in
...
"regular file"|"regular empty file")
ptxd_install_file "${file}" "${dst}" "${usr}" "${grp}" "${mod}"
"${strip}"
;;
Here is the content of the systemd_239_armel.ipk package:

The same files under platform-ec1c/root/ directory hierarchy have the same
permissions as above.
