Re: replacing makedev

We reimplement it because we have different needs.  For example,
the one I'm working on has the following bit of code:

ext = strrchr (file->d_name, '.');
if (ext == NULL)
	read_file (file->d_name);
else if (strcmp (++ext, os) == 0)
	read_file (file->d_name);

where 'os' defaults to linux, but can be set w/ MAKEDEV -o "netbsd".
Other distributions aren't going to want this, and there's no reason why
we need to share this; makedev isn't a mutable organism (well, it
shouldn't be, if done correctly).  The things that change will be in
/etc/makedev.d, and will be distributed amongst other packages

Conectiva uses the same MAKEDEV script we do.  Redhat uses their own.
Slackware doesn't even have a MAKEDEV.  Mandrake uses redhat's.  They
have different needs; trying to have a "one true makedev" seems almost
counterproductive.  If we conform to redhat's makedev, we break stuff;
if they conform to ours, they break stuff.  If we create a makedev w/
features from every distro, we create a bloated mess that will probably
end up being forked anyways (easier for distros to patch their rpms/debs
than to coordinate w/ upstream).

BTW, for those who don't speak C; the above checks if a filename has an
extension; if not, read it in; if so, check if the extension matches the
OS.  So, /etc/makedev.d/foo and /etc/makedev.d/bar.linux would be read
in, while /etc/makedev.d/baz.freebsd would be ignored (assuming the os
is linux).

Broad surveillance is a mark of bad security.
