Yeah, the directory layout changed somewhat in the newer versions of hal. Just create a directory called /usr/share/hal/fdi/policy/95userpolicy and put your XML file there. Technically, it should work. Then again, you could just change what you want in /usr/share/hal/fdi/policy/10osvendor/10-storage-policy.fdi

I'm just started to use gentoo so i'm fairly new to this and I'm a little affraid of changing scripts etc ;-)

I have already used .masked en .keywords very often. But I didn't know about .use . So it would be better to put it in the .use file then ?

Thanks for the advice Halfgaar !

The /etc/portage/package.* files are there for your configuration, they are not scripts or anything. And it is indeed better to put it there. USE=... and ACCEPT_KEYWRODS=... can completely mess up your system.

Ok thanks for the quick response and for the advice !

I meant by changing scripts, the hal emerge script.

This was the only time I used the USE on the prompt. But from now on I know better: it goes in the .use file.

The reason for this is this because when I do an emerge -uD world and there is a new version of Hal that it will compile again with the docs and maybe failling again ? And with the .use usage it will always compile without the docs ?
But then again maybe they fixed this problem in the next stable release and then I would never have docs if I don't check it manually (removing it from the .use file, checking if emerge don't fail, etc...)
Or is there a way to make the .use only work for specific versions of packages?

And I will read also the info about .use file etc.

Thanks man

Thank you! You are very kind !

I will read about it. And I have enabled the doc use flag in my make.conf. Because I thought, I'm starting to use linux and everybody tells me that you have to read a lot before you are getting anywhere. So therefor I enabled this use flag ;-)

I will stop talking about this, because this is a little bit of topic I think, but I just wanted to thank you !

ivman does not mount devices, but i know it has some months ago:

Hello,
I'm using the latest ivman, it works great, mounts everything what I need, but:

halfgaar · l33t Joined: 22 Feb 2004 Posts: 781 Location: Netherlands

Have you tried googling for the error?

Ah, I figured it out. I have the problem as well.

First a post containing all my problems with ivman. It's only 6 posts long. Now you know that cd drives possibly remain mounted after you eject them. Yes, this means that ejecting is possible when the drive is mounted. Ivman is supposed to unmount them, but when they are in use, by Konquerer for example, or by having it as your current dir in the console, the unmount fails, and you have to fix it as root.

The busy inode messages you get when a mounted drive is no longer available. Unmount the drive as root to let the messages stop.

I have asked this before, but why was fstab-sync replaced with ivman? This ivman stuff works exceptionally bad. It would appear that the intent is to have a system similair to Windows, where the user has to do nothing with mounting, and the OS gracefully lets the drive (or, in case of Windows, it's contents) appear and disappear on insertion and removal of CD's, but it doesn't work at all.

I've switched from running ivman as a user to running as root. Now it doesn't produce so many errors, but lack of ability to umount disk by user is annoying. Fortunately it's umountet when I press the eject button, but it isn't the best solution.

You forget, that when the drive is busy and you eject it, it's not unmounted. You'll get the errors again when that happens.

I'm not using ivman anymore because it doesn't add any functionality to what I do or need except allow me to eject a mounted cd/dvd via the drive button and automatically unmount it at the same time but that was working fine last I checked.

Are you guys running ivman as root via /etc/init.d/ivman and again as user when your desktop or wm loads? It needs to have both instances running to function properly.

I only run it as root. My KDE is too old to support it. I don't want to upgrade yet, I'm waiting for 3.5.2.

But even when running it as a normal user as well, that doesn't fix the stale-mounts issue.

I just checked ivman here... works fine, put a cd in, it automounts with not user intervention, viewd the files in konqueror, then I hit the eject button on the drive and it opened up, unmounted, and all is good.

This is the /var/log/messages after I started /etc/init.d/ivman as root, ran 'ivman' from a user konsole, and put in a cd.

halfgaar · l33t Joined: 22 Feb 2004 Posts: 781 Location: Netherlands

Now go to the cd drive in the console when the cd is inserted and try again...

Yes that causes the messages but I'd guess that would be expected since if you are cd'd to the directory where the media is mounted it expects the media to be there unless you cd somewhere else. With konqueror you're accessed via media:/ so it's not picky about it being mounted or not or where it's mounted even. It's either there or not there as far as it's concerned. I never access a cd/dvd/whatever via the cli anyway so I guess I would have never noticed this issue in this way and ivman doesn't add anything to what I need anyway so I haven't been using it for about 6 months.

You could probably work around it with a special rule and use the pumount command as long as the user has the right permissions.

With konquerer you can very easily go to the /media/ directory, instead of the media:/ handle. This is sometimes necessary for example when you want to access data on the CD with applications. Most applications don't know what media:/ and fail.

And there are countless other situations when a mountpoint could be in use. In my opinion, the way ivman is designed, is just flawed. It's just not going to work like windows where the data that exists on the cdrive is eloquently removed from OS access.

my cdrom drive seems to support the EjectPressed message:

Well, i just emerged it yesterday, but so far i am not disappointed. It does exactly what it is supposed to do. And i didn't even change one single config-file!

I will still test it a bit, but i am used to the console and it works fine there. I am also used to leave a directory before unmounting the connected device, so i still gotta see what happens when i forget that. But i gotta go to school now.

regards,

On my laptop I have a cdr/dvd drive. When I insert a cd ivman mounts the drive to /mount/cdrecord as user ivman and group plugdev. However when I insert a dvd it is mounted as user root and group root. Has anybody come across this sort of problem?

After playing around a little bit I notice this problem only occurs when using a data dvd produced by k3b. It is not even related to ivman. I tried manually mounting the drive using the plugdev group and ivman user but it still mounts with as user/group root.
