I've got an image for a AM3352 system based on Dylan and Arago and I'm
trying to switch to systemd for init.
So far I haven't had much luck.
First off I'm getting different results depending on where I turn it on.
I'm turning it on via the following 2 lines:
DISTRO_FEATURES_append = " systemd"
VIRTUAL-RUNTIME_init_manager = "systemd"
These two lines looks correct, though, if you're building a systemd-only
distro & image, you migth want to add:
DISTRO_FEATURES_BACKFILL_CONSIDERED = "sysvinit"
If I place these lines in my_image.bb file I seem to get a partial
install of systemd, systemd_udev is there and seems to run but that's
about it, there is no systemctrl journalctl and the sysvinit init
scripts still seem to be called.
And also on this point, make sure to check your PACKAGECONFIG values
for systemd. The optional utilities like networkd are not enabled by
default, and a bbapend of the systemd recipe is needed to enable them
via PACKAGECONFIG.
Cheers,

DISTRO_FEATURES is a distro (policy) configuration, and thus, can't be
modfied in a recipe. The correct way would be to add this in your own
my_distro.conf.
If I place these lines in either local.conf or my_distrobution.conf
all of the systemd utility seem to get installed and systemd startups
up but it's clearly not configured correctly.
Good that it seems to be installed OK.
For starters the systemd dbus isn't getting created and that seems to
lead to a whole host of other problems, including journald constant
spewing the following error messages:
[ 55.926223] systemd-journald[715]: Failed to write entry, ignoring: Argument

I don't know if it matters but this system has no display at all, it's
a strictly embedded installation.
That shouldn't really matter, I'm running systemd in headless setups.
I'd guess that you're getting some errors earlier than this in the
bootlog? Could you paste them?
Cheers,
Anders
