Hello fellow Ubuntuers, now that we have logind/uaccess and libudev1 in Ubuntu, it is finally time to update to a current udev version. This will bring a faster system boot as it does not call the modprobe, scsi_id, blkid and other programs a gazillion times, but instead has all these built in (through libkmod, libblkid, etc.). It will also get us rid of quite a few patches which were piling up to make our increasingly ancient udev work with the current kernel and plumbing.
I went through our current package and applied our remaining patches, initramfs integration and Ubuntu specific rules. There were two patches which were non-obvious: * avoid-exit-deadlock-for-timely-events: This was applied for http://pad.lv/842560 . Andy discussed that with upstream in http://comments.gmane.org/gmane.linux.hotplug.devel/17206 and as a result the whole TIMEOUT legacy stuff has been removed, so this does not apply any more. Also, firmware handling has changed quite a bit (e. g. recent kernels load it by themselves). So I dropped the patch. * avoid-exit-deadlock-for-dm_cookie.patch: This was applied as a kind of workaround for http://pad.lv/802626 (I think we really should stop having two udevs in the boot process, BTW), and further modified the code that avoid-exit-deadlock-for-timely-events already changed. I think I ported it correctly, but if you have an LVM setup, double-checking this can't hurt. There is one important change which warrants some discussion: By default, current udev now uses BIOS/vendor/slot number based names so that they are easier to identify, but more importantly, they have predictable names without the old 70-persistent-net.rules. My current package disables this for upgrades (to avoid changing any existing network configuration), but enables it for new installs. Stephane Graber mentioned that we might not want this as it might break too many tools which rely on the ethX naming; I can forward port the old generator for 70-persistent-net.rules (it's just a shell script) if we want. So before I land it in the archive I'd like to get a few more testing results on various machines. If you could install the packages from https://launchpad.net/~pitti/+archive/ppa (systemd is the only one for saucy in that PPA) and tell me how it goes, together with your machine/install config (UEFI, LVM, cryptsetup, etc.), I'd appreciate. Thank you in advance! Martin -- Martin Pitt | http://www.piware.de Ubuntu Developer (www.ubuntu.com) | Debian Developer (www.debian.org)
