eudev, fork of udev

March 08, 2013 — BarryK
I posted about this recently:

I am currently fixing the Arch Puppy build in Woof, and I ran into a problem with udev -- my udev PET package (version 167) only has '', whereas Arch requires ''. That was just the start of it.

When 'udev' was a separate package, there was '', and after merging into 'systemd' package it became ''. They are not compatible, you can't just create a symlink for

I want to keep using 'module-init-tools' for awhile longer, however Arch has gone over to 'kmod' -- well, apart from it's merits, they had to, as udev in systemd requires it.

I had a look at compiling 'systemd', with a view to taking out just the udev parts. The systemd developers say that this is do-able, however they don't make it easy. In fact, the pressure is there to adopt systemd.

Which I don't want to do either. I want Puppy Linux to stay with Busybox init. If I do move to anything else, it will probably be to 'minit', another init-like system.

I don't want to lose either, as there are some apps linked to it that I want to keep using.

My Wary Puppy doesn't even have dbus, but it seems that systemd requires dbus.

So, I turned to eudev, the fork of udev. Three of the eudev developers gave a presentation recently at a conference, and they were ganged-up-on by the clique of systemd developers. Then a lot of other people who haven't really got a clue, propagated the criticisms.

I took a good look at eudev. It is what it claims to be, "system agnostic". I was able to disable use of libkmod, as I am still using module-init-tools. I was able to configure it to build both and It does not need dbus.

The developers have stated that it is experimental and may be buggy, but I have tested it and it works fine so far.

This is how I configured it:
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var --sbindir=/sbin --libdir=/usr/lib --libexecdir=/lib/udev --build=i486-pc-linux-gnu --with-rootlibdir=/lib --with-firmware-path=/lib/firmware/updates:/lib/firmware --disable-introspection --disable-selinux --enable-legacylib --disable-libkmod --enable-gudev --with-rootprefix="" --disable-gtk-doc --disable-manpages --disable-keymap

Note, I disabled manpages as that failed to build.

Here are the PETs (963K, 372K):

Note to anyone not using Puppy Linux, those PETs do not have any rules in them. Puppy has his own set of rules, that are provided in the Woof build system.

The source package is in my sources repo:

I got the source from here:

Note, the last commit was about a month ago. I think that the developers got disheartened after being attacked. I would like to tell them that I like what they have done, and to keep at it.
Their eudev is actually going to be used in a distro, my Puppy Linux, at least on one variant.

I am strongly of the opinion that udev should never have been merged into systemd. Of course, the developers of most of the major distros could not care less, they have gone over to systemd and kmod. So it is a non-issue for them.

There are some things that have to catch-up, such as Busybox, then I will likely move to kmod. But not systemd -- what I have read about it, I don't like. My personal opinion of course.

Got to be doing something right to achieve this much interest, even if it's transient and poorly characterised data analysis! Congratulations. My guess is that the appeal lies in producing an OS that runs on [b]OLD[/b] kit, but might also run on some new junk rather than [i]vice versa[/i]? Everybody has old stuff kicking around but frequently it's the spoilt brats having too much dosh, shiny new lamps, lack of imagination, no commitment to recycling and, perhaps, upstairs deficiencies, to boot! In the present economic climate, which may extend for another decade, your continuing efforts are destined to succeed. Death to secure booting and the Wintel cartel...

"Well, I deliberately worded my post in an aggressive manner, so as to "stir the pot". Or, "ruffle a few feathers". I do get that wicked gleam in my eyes sometimes. Yes, I do hope that they keep working on eudev. It might only remain a niche player, but important nonetheless.

Indeed, some of my contacts hadn't heard of it nor realised the Mandrake/Mandriva & forks fiasco. Mint, Puppy, Debian, Fedora, SuSE seem entirely credible. Notwithstanding the accepted limitations of this method of data analysis." other methods could also be used to gauge popularity. 1. do a search for mageia on irc freenode and you will see that mageia is indeed well chatted. the red herrings appear to be, wait for it: puppylinux and mint. even PClinuxos beats puppy by far. 2. torrent download seeds. puppy fails miserable here too. while arch, ubuntu well deserve there ranking. so it would seem that it is puppy that is slanting the score more so than pclinuxos and mageia. images to come shortly.

"I believe that the popularity measurement by irc activity can be very misleading. IRC historically is used mostly by developers and actually channels and people/channel (usually the same people in many channels) reflect just that. See channels sorted by #people as an indication. [img][/img] Distrowatch on the other hand indicates interest/curiosity (but not necessarily use) by general audiences.

"remember we also have access to pupppy huh, what that? some unknown component? :) note ubuntu ahead of android and Linux 13392179 45.9 % ahead of Windows 12727953 43.6 % calling this a general audience population sample would be a stretch of belief by other, say news website stats.

"Distrowatch visits are understandably from computer enthusiasts/geeks (20/% with "unspecified" GNU/linux !!!) which may explain Puppy's popularity in distrowatch, but is still more general than IRC channels. No?

eudev continues

"I have received feedback from a couple of the eudev developers, and they will be continuing the development.

mint irc non freenode.
Username: aarf
"mint doesnt use freenode as its irc network so that is why there are so few mint users there. but a quick look at the official mint channel also says it is not exceptionally popular. but it was a good move by mint to get off of "freenode". can puppy do the same? seems anywhere would be a better network. all it would need is a push from the top. then puppy too might be more chatted.

eudev updated
Username: scsijon
"eudev-1_beta4 is out and dated 10 April. From reading a lot of messages across a number of bbs's it seems that the gentoo variety is suppose to have a 'switch' to de-systemd your systemd system, but not sure what stage it's at. It would be interesting to try that. It would certainly be interesting to build a very basic puppy with it instead of udev and see what it's like. I might rebuild my myz puppy (minimal racy) up to racy 5.5 and then see what happens with a eudev parallel, now the final beta of mage2 is out and joe has 'quietened down' with the jwm updates.
