Hello together, as you all may have already noticed, as of version 183 the udev sources has been merged into the systemd sources. At the time I read the first announcement from Kay Sievers that doesn't sound too bad [1] to me, because I got the impression that it would be easy to extract udev from systemd. Unfortunately in practice the whole thing looks like a big, bad issue. It's not possible to configure systemd in a way that udev can be build standalone, but you have to build the complete systemd stuff and manually extract what is needed for udev. Kay's comment on to that issue sounds quite different than the first announcement to me [2]. In the meantime we can see two attempts of other people to submit patches [3][4] to improve the situation, but with no "official" comment yet. Currently we don't have a practical issue with all of that, because we can stick with udev 182 for now. You may ask why I wrote all of this, it's just for your information and to summarize the whole situation. For me the whole udev/systemd source merge looks like a crude effort to force people to use systemd. But what can we do? Good question, in the long run it will be impossible to use udev standalone IMO, so we either have to switch to it or do something completely different. One possiblity might be mdev, a dynamic device/node creation program that comes with busybox, see [5] for a short description, together with devtmpfs which is a kind of devfs, see [6]. Btw, I'm not sure but it looks like our Per had put a comment to that article ;) [7] We, that means Jose, Fredrik and me, have done some initial tests with mdev, it looks not so bad at all. We will continue on testing it and report here our experiences. Thanks for the attention and a nice weekend to all.
