Attached below, with debug output by adding set -x to the scripts. 

One thing remains to do: The file
/etc/dhcp/dhclient-exit-hooks.d/rfc3442-classless-routes should not be
run on GNU/Hurd (or should be adapted to not use /sbin/route). Now it is
called but does nothing.

It does not make sense to use construct like, created by
using ptom (softlink to netcfg) since inetutils does not support this
synstax. (I downloaded the udebs netcfg_1.60,
libdebconfclient0-udeb_0.154 and libdebian-installer4_0.76 to try it
out). Likewise, kfreebsd does not use this construct either, even if the
code is still there in the udeb.

Of course the scripts should be tested in other environments than under
qemu like I did. And, the udebs within the Debian installer of course.

No idea, I had not installed GNU/Hurd by then. The patch you sent last
year was for dhcp3, things seems to have changed a lot with version 4 of

I've spent enough effort on this for now. I'll send a patch as a bug
report as mentioned earlier. Please test the patches and review the
modified scripts.
