I had gotten curious enough about this go to the source, too. I looked SysVinit up on
Freshmeat, got an URL for the source (www.ibiblio.org), and downloaded the
SysVinint-2.78.tar.gz.
But after downloading and untarring, I couldn't find anything that looked like it
would create these files (/halt, /poweroff). As it turns out, the comments inside the
halt.c file (in the SysVinint-2.78 tarball I downloaded) identified it as version
2.74, dated 24-Feb-1998. I guess I must have gotten an older version of the halt
source. You looked at the source from the RH7.0 src.rpm? The section of code you
quoted definitely isn't in the file I looked at.
But anyway, thanks for figuring out the answer to my last question.
The original issue, I think, was that someone (sorry, I don't remember who) wanted to
know why upgrading from 6.2 to 7.0 changed the behavior of the `halt` command.
