udev-126 puts devices in /usr/local/dev

udev-126 puts devices in /usr/local/dev

[Aras Vaichas]

Hi there,

I just updated from 124 to 126 and now all my /dev entries are being
created in /usr/local/dev ...

I ./configure'd with the default settings and I am cross-compiling udev
in a Scratchbox environment.

Is there a configuration option that I should be setting?

If you don't pass any special options (such as prefix=/), the behavior
of putting device nodes in /usr/local/dev is indeed correct (it's useful
for e.g. debugging udev without screwing up the real /dev).

FYI you can override this by editing the udev configuration file (e.g.
the one in /usr/local/etc/udev/udev.conf if you don't pass stuff
to ./configure), e.g. just put

 udev_root="/dev"

in the file and you should be all set.

This really looks like an excuse for an autoconfiscation bug.
I have been maintaining an udev package for over four years and I never
dreamt of rebuilding it with a different value of udev_root just for
testing.
It's much easier to set $UDEV_ROOT when debugging instead of forcing
every package maintainer to set $prefix.

Hah, thanks. Silly me, I should have read the man page for that setting.

I also wanted to check that this was the expected behaviour.

I personally would design it so that the default configuration would
install into the default location.I think that would adhere better to
the "Rule of Least Surprise".

I'm currently assembling a whole custom Linux distribution for our
embedded product, and 9-times-out-of-10 I can just call ./configure for
each package and everything works as expected. Anyway, just my 2 cents.

The gentoo package now calls configure with these params:
--prefix=/ --includedir=/usr/include

The only thing I explicitly patched is the path to the pkgconfig file. I think 
it should be in /usr/lib/pkgconfig and not in /lib/pkgconfig.

Huh? Why? Let prefix stay as usr, as usual, and set exec-prefix, as
suggested in INSTALL. Just take a look at autogen.sh.

Ah, that simplifies it.
Thanks
