Public bug reported:
systemd_218-6ubuntu1_amd64.deb and later work ONLY with USB networking
devices when booted from Dracut. Dracut network module is NOT in use, and
binaries needed to connect to the network do not appear in my initramfs, yet
systemd version loaded from it determines whether or not network can be
connected. With an AMD Athlon II x4 machined and a Gigabyte AMD motherboard
(785 series I think), I get the systemd networking unit entering a failed
state, and the wired network cannot be turned on. On an Intel Atom Pine Trail
netbook the wireless attempt to connect to the network but hangs on requesting
an IP address from the router, never completing. Rolling back systemd to
systemd_218-5ubuntu2_amd64.deb always fixes this and brings back normal network
connectivity. Finally, an AMD bulldozer machine connected by a USB wifi device
has no trouble at all with the newer builds of systemd.
systemd_218-5ubuntu2_amd64.deb , which came out Jan 23, seems to be the
last good version. Same upstream version of systemd, apparently just
build-time changes caused this.
I'm not sure if this bug will appear with a normal Ubuntu initramfs-
tools initramfs (I use Dracut with systemd in the initramfs), but I
bring this up because my /boot partition is not normally mounted (so as
not to corrupt a monitored hash value) and which version of systemd is
in the initramfs, not the version on disk, determines whether or not
networking functions on my machines. I do understand my setup has
diverged a lot from normal Ubuntu, someone should see if this problem
exists in a normal Ubuntu install. If not I will need to find out what
changed(possibly a udev rule?) and revert it myself in all later
versions.
I've been using systemd with dracut/systemd in the initramfs since last
May, I now rely on it to run a parallelized version of my multi-
encrypted disk unlocking program and am not about to revert it.
Initramfs-tools seems to be unable to cope with multiple asynchrounous
instances of cryptsetup, while dracut/systemd handles it just fine.
