I'm the first to admit, I don't understand systemd yet.  I wanted to know - how do you know what services you're starting up?  What's the systemd equivalent of chkconfig --list?  Well, maybe I found it - just type "systemctl" with no switches.  So check out the differences between fw1 and fw2.  I have no idea what this means but I think it might be relevant.  

First, systemctl on fw1.  Notice everything is loaded and active except a mystery service named rng.service I don't think we care about.  I'll paste in all 118 lines from fw1.  Now scroll down and look at the extract from fw2.  So nobody is forced to wade through 200+ lines of output, I'll only paste in the relevant service that failed on fw2, named firewall\x2dscripts.mount.  

This same service works on fw1, fails on fw2 with a status of "No such file or directory" - status posted below.  I wonder what it does?  That backslash character in a filename seems fishy.  The only reference I can find anywhere is in a directory, /run/systemd/generator.  I'll paste in what it looks like at the very bottom.

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

110 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.
lines 94-118/118 (END)

To save a headache, now just the extract from fw2

[root at chicago-fw2 ~]# systemctl
