Thank you Petter.

I put the files into a directory called 'sysvinit.2.86.ds1,  cd 'cd 
src'  then 'make halt'.

You can see exactly the object and executable files, I've uploaded the 
whole tree directory to


Just look in 'src' from there, and you can get everything.

I'm still new to Linux, really.  So I don't understand the references to 
dpatch and so on, and I really don't know very much about sysvinit 
tools.  I'm sorry I can't answer your second question.

But one thing I do know for certain:   The version of halt shipped with 
Etch breaks the wake-on-lan function because it doesn't actually make the 
system call to do what the command flag directs.  I don't know if it also 
fails to sync or make other OS calls.  Also, I do know for sure that the 
version I've uploaded there works perfectly with exactly the same commands 
on the command line that fails to work in the version shipped in Etch.

Thanks for helping!
