udev 063: when ?

Colossus · 2005-08-23 09:38:55

Hi,

please accept my aplogies if I posted in the wrong place. Udev 063 is out but the archie package not, what is the problem ?

Thanks,
Colossus

The problem is most likely one of two things, The package hasn't been flagged as out of date yet or the package maintainers are just a bit busy at the moment and will update udev when they can. I have checked the arch home page for the latest version of udev and it has been flagged as out of date so a new version should be with us soon.

Package updates are pretty rapid here so I expect the wait will be short.

More than two months have passed since the 063 came out, the problem shoud be another one.

063? There is 068 now:

In fact there is a new udev version released every few days...

Hopefully they are close to perfect udev since TODO file is quite short:

This is a short list of things that needs to be done. They are in no specific
order. I will gladly accept patches for any of these items, or any other stuff
people offer up.

- more documentation (can never have too much.)
- persuade the distro packagers to submit their changes (or just steal them
if we can find them...)
- do early boot logic (putting udev into initramfs, handle pivot-root,
etc.)
- solve world hunger

On the other hand the last thing may take a lot more time to acomplish ;-)

Ok now I understand why the package has not been built yet.

Now, after browsing example new udev rules (gentoo version) I'm not so sure it's going to be easier. New rules and tools are less readable IMO.

FYI a good source of information about latest releases of udev and its bugs (next to docs from the sources) is this gentoo thread:
http://forums.gentoo.org/viewtopic-t-35 … t-100.html

@Colossus: I'm not one of the devs and the reason for delaying new udev package may be different. It was only my observation.

Very nice link, very informative thank you lanrat. Do you how can I have /dev/dvd pointing to /dev/hdd in group optical ? I created a custom rule in /etc/udev/rules.d/ with this content but the group is always root:

KERNEL=="hdd", SYMLINK="dvd" , GROUP="optical"

Thank you,
Colossus

I think you should create /etc/udev/rules.d/010.udev.rules and put something like this inside (don't change standard arch udev.rules file):

BUS=="ide", KERNEL=="hdd", SYSFS{removable}=="1", PROGRAM="/bin/cat /proc/ide/%k/media", RESULT=="cdrom*", NAME="%k", GROUP="optical", SYMLINK+="dvd cdrw", OPTIONS="last_rule"

or a shorter one:

BUS=="ide", KERNEL=="hdd", NAME="%k", GROUP="optical", SYMLINK+="dvd", OPTIONS="last_rule"

Restart udev as root with udevstart. Now you should have root:optical for /dev/hdd and root:root for /dev/dvd (it's a symlink so it's normal).

My custom udev rules:

There are more examples in the forums and wiki.

This is what I DON'T want: root.root I need root.optical for /dev/dvd otherwise xine will not access my dvd disc.

Thank you,

I don't think it works that way... I'm pretty sure permissions on a symlink are only for changing the symlink, and when opening "/dev/dvd" is will use the permissions associated to "/dev/hdc" - I may be wrong though.

lanrat · 2005-08-23 23:10:08

ls -l /dev/dvd
lrwxrwxrwx  1 root root 3 2005-08-23 20:49 /dev/dvd -> hdc
ls -l /dev/hdc
brw-rw----  1 root users 22, 0 2005-08-23 20:49 /dev/hdc

and any user on my system can burn dvd and so on...
