connections takes place before the connection acquires its names.

starvation of other events is possible, if one of the inner µhttpd

a 64bit BE machine where accessing 32bit values as 64bit and vice versa
will explode.
Also, while we are at it, be a bit more careful when dealing with the
64bit cookies we expose and the 32bit serial numbers dbus uses in its
payload.

nspawn: make host0's MAC address persistent
We still need to make sure that no two MAC addresses are the same, so we use
a logic similar to what is used in udev to generate MAC addresses, and base
it on a hash of the host's machine ID and thecontainer's name.

getty: Start getty on 3270 terminals available on Linux on System z
Add the first 3270 terminal device that is associated with the Linux preferred
console to the list of virtualization consoles. This is required to
automatically start a getty if the conmode=3270 kernel parameter is specified
for Linux on z/VM instances. Note that a queued upstream patch also enable
the 3270 terminal device if it is associated with the Linux preferred console.
How
To successfully start agetty on a 3270 terminal, a change in the agetty
parameter order is required. Previously, agetty would started like this:
/sbin/agetty --keep-baud 3270/tty1 115200,38400,9600 TERM
The agetty program interprets the "3270/tty1" as baud rate and fails to start
with the "bad speed: 3270/tty1" error message. Fixing this in agetty is more
complex rather than reordering the command line parameters like this:
/sbin/agetty --keep-baud 115200,38400,9600 3270/tty1 TERM
According to agetty sources and "agetty --help", agetty accepts the "tty",
"baudrate tty", and "tty baudrate" specifications.
P.S. The "tty: Set correct tty name in 'active' sysfs attribute" introduces
a change to display the terminal device which is associated with the
Linux preferred console. This change helps to let systemd handle this
particular case only. Without the changes of this commit, no additional
3270 terminal device can be managed by systemd.
