 +  [changes brought forward from 239-9+rpi1 by Peter Michael Green <plugwash@raspbian.org> at Thu, 20 Sep 2018 20:22:45 +0000]
 +  * Disable testsuite, it fails on some of our buildboxes (probablly because of
 +    old kernels).
 +  * Add breaks on raspi-copies-and-fills, it doesn't seem to get on with
 +    this version of systemd/udev.
 +
 +  [changes brought forward from 241-1+rpi2 by Peter Michael Green <plugwash@raspbian.org> at Tue, 02 Apr 2019 19:29:26 +0000]
 +  * Bump "breaks" on raspi-copies-and-fills to << 0.12
 +    (raspi-copies-and-fills was reverted by the raspberry pi foundation)

+ 
+   * udev-udeb: setup /dev/fd, /dev/std{in,out,err} symlinks.
+     As systemd-udevd no longer sets them up itself, we create them manually
+     after mounting devtmpfs. This avoids breaking applications which expect
+     those symlinks. (Closes: #975018)

+     networkd adds them". (Closes: #985510)
