(Most interfaces appear that way with udev.) An old system that has "auto eth0" here will work fine though, unless eth0 is in fact a hotpluggable interface, in which case hotplugging it will not work. Is there a case where hotplugging would have worked in sarge and won't in etch, with the old config? That would be one for the release notes. > ------------ > > #2. > Also noticed that on my old system /etc/network/run is a symlink to > /dev/shm/network.

Perhaps ifupdown.postinst's tests for /dev/shm fail when run in the d-i environment? Sounds like a likely bug, since d-i does not set up a /target/dev/shm. > #3. > On new installs, the contents of /etc/default/rcS have changed.

Currently initscripts only puts the file in place if it does not yet exist, and never updates it. -- see shy jo
