            Bug ID: 15847
           Summary: Systemd: Incorrect Permission on /usr/lib/systemd
           Product: buildroot
           Version: 2023.08.2
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: minor
          Priority: P5
         Component: Other
          Assignee: unassigned@buildroot.uclibc.org
          Reporter: justin.brown@fandingo.org
                CC: buildroot@uclibc.org
  Target Milestone: ---

I'm trying to use systemd as my init and systemd-networkd as my connection
manager. There appears to be a problem with the file permissions that prevent
networkd from starting. 


CONFIG:
=======

I'm tracking origin/master and am up to date with fd41e442f0f from Nov. 7th. My
defconfig is qemu_x86_64_defconfig with two modifications: BR2_INIT_SYSTEMD=y
(including BR2_PACKAGE_SYSTEMD_NETWORKD=y) and a BR2_ROOTFS_OVERLAY that
provides a etc/systemd/network/01.network basic DHCP unit file. (Plus the
additional both required and optional linux.config modifications for systemd
specified at https://github.com/systemd/systemd/blob/main/README.) 


PROBLEM:
========

The systemd package creates a systemd-network user, and the
systemd-networkd.service unit executes as that user. However, the file
permissions prohibit this non-root user from executing
/usr/lib/systemd/systemd-networkd:


# ls -ald /usr/lib/systemd/
drwxrwx---   13 root     root          2048 Nov  9 10:10 /usr/lib/systemd/

# ls -al /usr/lib/systemd/systemd-networkd
-rwxr-xr-x    1 root     root       1579456 Nov  9 10:10
/usr/lib/systemd/systemd-networkd


Note that the /usr/lib/systemd directory does not allow the necessary o=rx
permissions for a non-root user to access these binaries.


REQUEST:
========

I'm not well versed in writing makefiles, yet. But from a sh perspective, the
solution seems to be that the systemd package makefile needs to do the
equivalent of:

chmod o+rx /usr/lib/systemd
