I am trying to make the serial console automatically log in a user on

/lib/ is package manager territory, you should never edit files there,
the package manager will otherwise override your changes without hehow
to correct thissitation.
Instead, copy /lib/systemd/system/serial-getty@.service to
/etc/systemd/system/serial-getty@.service -- /etc is administrator
territory, and unit files stored there will automatically override
unit files by the same name in /lib.
I had actually tried this (or several variations on this), but it was
not producing the desired results.
I tried again using exactly what you suggested. For this example, I
just used 'root' user for testing. Below are snippets of the steps I
performed:
--------------------------------------------------------------------------
cp /lib/systemd/system/serial-getty@.service
/etc/systemd/system/serial-getty@.service
vi /etc/systemd/system/serial-getty@.service
diff -u /lib/systemd/system/serial-getty@.service
/etc/systemd/system/serial-getty@.service
-----------
[Service]
-ExecStart=-/sbin/agetty -s %I 115200,38400,9600 vt102
+ExecStart=-/sbin/agetty -s --noclear --autologin root %I
115200,38400,9600 vt102
-----------
[root@localhost ~]# systemctl daemon-reload
[root@localhost ~]# exit
logout
Fedora release 18 (Spherical Cow)
Kernel 3.6.10-8.fc18.armv7hl.tegra on an armv7l (ttyS0)
localhost login:
( note: still prompts for login )
[root@localhost ~]# reboot
:
Fedora release 18 (Spherical Cow)
Kernel 3.6.10-8.fc18.armv7hl.tegra on an armv7l (ttyS0)
localhost login:
( note: again, after reboot, prompts for login )
[root@localhost ~]# cp /etc/systemd/system/serial-getty@.service
/lib/systemd/system/serial-getty@.service
[root@localhost ~]# systemctl daemon-reload
[root@localhost ~]# exit
logout
Fedora release 18 (Spherical Cow)
Kernel 3.6.10-8.fc18.armv7hl.tegra on an armv7l (ttyS0)
localhost login: root (automatic login)
( note: works as expected, autologin )
[root@localhost ~]# reboot
:
Fedora release 18 (Spherical Cow)
Kernel 3.6.10-8.fc18.armv7hl.tegra on an armv7l (ttyS0)
localhost login: root (automatic login)
( note: works as expected, autologin.
also, note that the change is persistent; survives reboot. )
--------------------------------------------------------------------------
So if I make the change only in /etc it does not seem to work. If I
make the change only in /lib it works, but does not survive reboot. If I
make the change in both, it works and survives reboot.
I assume I am making some mistake in the process, but it is not obvious
to me what I'm doing wrong.
This is a headless system, so I only have a serial console for access.
I do pass "console=ttyS0,115200n8" on the kernel command line. I am
running systemd-195-15.fc18.
Please let me know what I'm missing.
Thank you,
