If you used a 10.3 image, that looks good.

I suppose that'd be this instead (“$online” vs. “$onlink”):

Could you please perform an extra check for us?
What happens if you change this instead:
--- a/debian/tree/busybox-udeb/etc/udhcpc/default.script
+++ b/debian/tree/busybox-udeb/etc/udhcpc/default.script
@@ -68,7 +68,7 @@ case "$1" in
# special case for /32 subnets, use onlink when adding routes
[ ".$subnet" = .255.255.255.255 ] \
- && onlink=onlink || onlink=
+ && onlink="onlink dev $interface" || onlink=
for r in "$router"; do
ip -4 route add default via "$r" $onlink
done
(The path is taken from the git source tree, please modify the same
file you've toyed with.)
That would make the change more mergeable (as it would be limited to
cases where we indeed have a /32) than the quick fix you've tested
successfully, which would only be valid for such /32 cases, I think?
(You can safely pretend I'm not used to that particular option.)
Cheers,
