As for the question of vol_id vs blkid, I would really like to know why it was changed from Debian in the first place..As Theo noted: I assume there was *some* reason that util-linux decided to break from Debian and use the vol_id library instead of blkid, but I believe that was an incorrect decision. libvolume_id and libblkid sometimes give different answers as to the content of the same block device. This can lead to different opinions as to which block device has a given UUID. libblkid was used by the base tools such as mount and swapon which mount from /etc/fstab. But libvolume_id was used by the higher level tools such as udev and HAL which mount hotpluggable devices. That didn't cause too many problems. But then we switched to UUID-based mounting; our initramfs is udev based, so that means we use libvolume_id to mount the root filesystem by UUID. It also means we use libvolume_id to resume from hibernate, which is stored in the swap partition. Having mount and the initramfs disagree about which was your root partition, and having swapon and the initramfs disagree about which is your swap device... Bad Things Happened. So to solve the problem, we standardised on one library. Since SuSE had already written the patches, and util-linux was going through the util-linux - util-linux-ng hiatus, libvolume_id was the one we picked. If the winds had been blowing from the opposite direction that day, we'd be having the same argument about breaking from Debian and patching hal, udev, initramfs, grub, etc. to use libblkid instead of libvolume_id. I can't please everyone ;-) The real problem is that we have two different libraries for doing the same thing. Actually, that's not entirely true. All libvolume_id contains are block device probing functions; you start off with a known block device (/dev/sdc1, for example) and ask it what it contains. libblkid is a bit more intelligent, it has a cache of known block devices and you can ask it for known UUIDs. If it doesn't know, it might scan new block devices; and if it does know, it double-checks to make sure it doesn't return you the wrong data. SuSE's patches (which we inherited) to util-linux get around the fact that libvolume_id doesn't behave this way by actually not using it at all. Instead they map UUID= and LABEL= mounts into /dev/disk/by-uuid and /dev/disk/by-label paths. These are maintained by udev based on its own probing calls with libvolume_id. Obviously because they're maintained by udev, there's a big drawback - it doesn't know if the filesystem changes. And that's why you have to reboot (or write the word change to the uevent file of the block device). That sucks. So the optimum future is to merge libblkid and libvolume_id; we only need one library. The final library should have a superset of both functionality. You should be able to ask it for information about an individual block device (and have as wide a range of support as libvolume_id does now), and you should be able to ask it for a UUID or LABEL using its cache.

Thank you Scott-- That explains in a way that makes sense to me--As of right now, having EXT4 work with the system in it's present form is far better that not having it working at all.I do look forward to the day that both libraries are blended together to avoid the reboot to see change stupidity :) On a side note--looking at bootchart--I see a measurable difference in grub to gdm--with the same kernel, there is a 3 sec difference using EXT4. I can send you runs to look at if you wish...my system loads quite a bit with the current kernel went from 42sec to 39sec. I know that 3sec isn't earth-shaking, but with the push to shave boot time it is 3sec quicker just by changing filesystem---So another plus in EXT4's column.. -- In order to support ext4, util-linux must use blkid (and not vol_id) https://bugs.launchpad.net/bugs/197311 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 197311] Re: In order to support ext4, util-linux must use blkid (and not vol_id)
At the time when I made the statement in the EXT4 HOWTO, vol_id didn't understand difference between ext4dev and ext4 filesystems. The bigger problem which is a major issue for people like me who are creating plenty of test filesystems is that vol_id patches to mount has the Windows-like property that newly created filesystems won't work until after you reboot. Personally, if you are willing to accept Windows- like flaws, you should use Windows. I am constantly creating and destroying filesystems, and the blkid libraries will detect and be able to resolve LABEL= and UUID= arguments right away. The vol_id patches to mount will fail to resolve LABEL= and UUID= parameters for newly created filesystems until you reboot, or give some magic command to force the vol_id subsystem to recreate and reprobe the /dev/disk/by-uuid and /dev/disk/by-label directories. Personally, I can never remember the magic command, and arguably, you shouldn't have to remember said magic command, especially when it's easier to recompile and replace util-linux with one that is compiled to use blkid. After all, if I was willing to deal with systems that require reboots before they function correctly, I'd be using Windows. :-) -- In order to support ext4, util-linux must use blkid (and not vol_id) https://bugs.launchpad.net/bugs/197311 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
