Package: makedev
Version: 2.3.1-82
Hello,
since a while makedev checks for udev presence before it does anything.
Unfortunately it does also detect udev when there is surely no udev
currently present on the system:
r...@darkside:~# uname -a
Linux darkside 2.4.27 #1 Thu Dec 22 21:52:46 CET 2005 i686 GNU/Linux
r...@darkside:~# ps -ef | grep udev
root 9107 2584 0 21:21 tty1 00:00:00 grep udev
r...@darkside:~# cd /dev && /sbin/MAKEDEV raw1394
.udevdb or .udev presence implies active udev. Aborting MAKEDEV invocation.
As you can see, I'm currently running a 2.4 kernel, which quite surely
has no udev running. This is also proven by the second command :)
Nowadays, makedev refuses to run because there exists a /dev/.udev
directory. However, this directory is created by the udev preinst script
and is thus always there on a Debian system with udev package installed.
Perhaps a better probe would be to check if /dev is mounted to a tmpfs or
something like that. Perhaps there is also some udev tool to check it's
presence, I don't know.
Btw: It's also not a good idea to rely on ps -ef | grep udev because
the udev package sometimes starts some udev daemon process on upgrades
(for whatever reason) even if the system is not udev-compliant at all.
regards
Mario

udev does not do this anymore.

And this neither.
