Hi, I'm not sure if this is a bug in preseed or netcfg. When doing preseed wheezy installs, we came across an issue using late_command. netcfg now has a 55netcfg-copy-config in finish-install.d which unconditionally overwrites /etc/network/interfaces. This makes it impossible for the late_command to ensure that this file is correct. I'm not sure if the netcfg script should be moved earlier, the late_command script later or whether netcfg should just check for the existance of e/n/i and not overwrite it if it's been put in place. This caused us a few issues during initial boot for various automated installs until we worked around it with a local hack of running an extra script from a local udeb after 55netcfg-copy-config. Thanks, Mark
