armv7 systemd

(20:21:39) rber@freenode: Hey
(20:22:18) rber@freenode: I observed that with latest and greatest on all branches there is something strange going on with networking/systemd
(20:23:04) rber@freenode: first I saw that I was not able to ping anymore anything from within my docker container
(20:23:45) rber@freenode: then accidentally I saw, that when I passed ip addresses via the kernel command line it suddenly worked again as it should
(20:23:47) rber@freenode: hmmm
(20:24:42) rber@freenode: now I added this dummy wired-network=unhappy: console=ttymxc1,115200n8 root=/dev/mmcblk0p1 rw rootfstype=ext4 rootwait noinitrd nohlt panic=1 wired-network=unhappy
(20:25:37) rber@freenode: so I can filter on it in /lib/systemd/network/80-wired.network
(20:26:00) rber@freenode: [Match]
(20:26:06) rber@freenode: Type=ether
(20:26:15) rber@freenode: KernelCommandLine=!wired-network
(20:26:24) rber@freenode: and voila -> it works ;)
(20:26:49) rber@freenode: So I am a little bit puzzled who does the DHCP magic then ;)
(20:40:44) rber@freenode: I completely removed /lib/systemd/network/80-wired.network and still everything is super happy ;)
(20:41:23) rber@freenode: So I guess either systemd has learned some new tricks or scripts from meta-virt and 80-wired.network don't like to coexist ;)
(20:52:09) rber@freenode: I erased just for fun everything under /lib/systemd/network/ and everything works fine, including docker ;)
(20:52:42) rber@freenode: I'm booting with a rootfs from SD card
(20:59:04) rber@freenode: I can even boot with with a rootfs over nfs without /lib/systemd/network/80-wired.network and KernelCommandLine=!nfsroot which was definitely not the case in a previous systemd version
(21:30:37) rber@freenode: all this was for arm32
(21:31:01) rber@freenode: on arm64 it looks like 80-wired.network is actually needed and does what it is supposed to ;)
