This is in the defconfig (CONFIG_UDHCPC_DEFAULT_SCRIPT). We might be 
able to get around it by passing 
-DCONFIG_UDHCPC_DEFAULT_SCRIPT=${datadir}/udhcpc/default.script as a CFLAG.

It would make it a bit harder for someone to change the script name for 
their distro. Should just leave it up to distros to fix the script name, 
or should I force it as a CFLAG? (BTW, in my distro I pass a flag to 
udhcpc to use an entirely different script path.)

I've also found it makes life easier to have symlinks for /usr pointing 
to ., and /sbin pointing to /bin. It means if I miss a hardcoded path in 
a binary like this, the package still works. But I have to chase down 
any packages that actually install files to /usr or /sbin -- otherwise 
when they're upgraded, dpkg removes the symlink and creates a /usr/bin 
or /sbin with one file in it :)
