[systemd-devel] systemd v228 errors: "Failed to enqueue exit.target job: Transaction contains conflicting jobs 'start' and 'stop'" ?

[PGNet Dev]

I'm booting a

	systemctl --version
		systemd 228
		+PAM +AUDIT +SELINUX -IMA +APPARMOR -SMACK +SYSVINIT +UTMP 
+LIBCRYPTSETUP +GCRYPT +GNUTLS +ACL +XZ -LZ4 +SECCOMP +BLKID -ELFUTILS 
+KMOD -IDN

OS instance.  Atm, it's a Xen DomU vm guest.

It's a DIY-build instance of current systemd for a stable distro 
release; @ distro has no apparent interest in supporting it.  Despite 
that, I'm trying to get it working and cleaned up for my own use.

On boot, I see these in logs

	dmesg

The deps are a bit convoluted at 1st look.

What in that config's causing the

	Transaction contains conflicting jobs 'start' and 'stop'

fails?
