openSUSE 12.3 installer formatting encrypted devices

Leave a comment

Hi, this morning I wanted to replace my openSUSE 12.2 by openSUSE 12.3 doing a fresh installation from a USB-stick (using a recent image of a KDE-live system). I am using an encrypted partition to store the volumes of a LVM-volume group (root, home and swap). root should get reformatted (from btrfs back to ext4), but of course I chose to keep my home-partition, it should get reused without being formatted. I entered this setup in the graphical installation program (YaST installer). I had done that before, quite often, what should go wrong? I went on not noticing the entry “Set up encrypted DM device on /dev/sda2”. What does that mean? Will it create some entries in configuration files for handling the encrypted device? No, it means that it will try to reformat the entire encrypted partition using “cryptsetup luksFormat” thus wiping out all volumes stored there although it was only told to format a single volume. Of course my last backup was quite old… but I was lucky: When reinstalling I always mount my home-partition–for accessing my files but also for noting when the installation program tries to touch the volume. I could not imagine that this would happen and thought this would be a quite useless precautionary measure–but actually this saved my day and not only this day: The installer (or cryptsetup or some layer in-between) noticed that there was a mounted partition using this device and refused to format /dev/sda2. First I did not understand the error messages but then–when realising the situation–I was shocked. Nervously unmounting the partition would have caused a total loss.

Afterwards there were even more surprises: This is a known bug! It had been reported before the release of 12.3. According to the report it can even wipe out your data although you did not press the button to start the installation! And it also causes the formatting of luks-encrypted devices which are completely unrelated to the installation—they just have to be open (later I retried the installer, I had plugged in an external hard drive containing an open encrypted LVM containing ext4/btrfs-volumes, I did not select it in the installation, but the installer wanted to format the partition (and it still wanted to format the partition containing my root-volume, although there was no btrfs-volume left iirc)). The bug had been marked as critical and as a potential “ship stopper”–but then somebody decided that encountering this bug would be too unlikely! Well, they might not have known all situations where this bug can occur and the particular steps to reproduce described in the report may appear unlikely and the bug may have been there before without anybody complaining. But, seriously, they wanted to risk total data loss just because a particular situation seems to be unlikely–although it actually happened? And of course you never know for sure whether such a critical bug may affect more situations than you thought.

The bug has been fixed in the libstorage-codebase before the release. However, it

Electronic Dungeons and Dragons Gauntlet is the Nerdiest Thing Ever

Leave a comment

You know that feeling: the group is together, late on a Thursday night, and somehow you’ve managed to lose some dice. But have no fear! As mentioned by Gizmodo, the fine folks at ThinkGeek have come up with a plan to always keep you rolling. The +10 Electronic Dice Barbarian Gauntlet isn’t just a fashionable accessory, it’s also a set of virtual dice.

While the acceptance of electronic dice over good old-fashioned d20 rolls is a question probably best left to your DM, the gauntlet is actually a great idea. Not only can you roll a single die — all the way up to d100 — you can also roll a pair of dice by simply flicking your wrist. The gauntlet can also be used as a digital watch, or a dual-counter, in case you’re playing a game of high-fantasy Uno.

Gerfried Fuchs: Backports Integrated Into The Main Archive

Leave a comment
Flattr this

Dear users and supporters of the backports service!

The Backports Team is pleased to announce the next important step on getting backports more integrated. People who are reading debian-infrastructure-announce will have seen that there was an archive maintenance last weekend: starting with wheezy-backports the packages will be accessible from the regular pool instead of a separate one, and all backports uploads will be processed through the regular upload queue (including those for squeeze-backports and squeeze-backports-sloppy).

For Users

What exactly does that mean for you? For users of wheezy, the sources.list entry will be different, a simple substitute of squeeze for wheezy won’t work. The new format is:

deb http://ftp.debian.org/debian/ wheezy-backports main

So it is debian instead of debian-backports, and offered through the regular mirror network. Feel invited to check your regular mirror if it carries backports and pull from there.

For Contributers

What does it mean for contributing developers? Uploads for backports are no longer to be pushed to backports-master but to ftp.upload.debian.org, like any other regular package. Also, given that the packages are served from the same archive install there is no need to include the original tarball in the upload any longer because the archive knows it (Squeeze and beyond).

Also, given that the upload goes to the same upload queue, there is only one keyring used anymore, so no more pain with expired or replaced keys. We though still keep the rule of adding your UID to an ACL list (this also includes DM additions). This is mostly only to give us the chance to remind you that uploads to backports are directly available for installation onto stable systems and you thus should take special care there. We carefully tried to take over the old ACLs, in case you can’t upload anymore, please tell us so we can look into the issue.

I’ve mentioned wheezy-backports (and squeeze-backports-sloppy) a few times here already, and you might wonder when it will be available. Technically, it is available from now on. Practically, while you could already upload to it, the set up of the buildd network is more painful than expected, so please allow the Buildd Team some days for setting them up.

The upload rules for wheezy-backports are the same: packages that are in the next suite are accepted. Given that Jessie isn’t created yet, we want you to think about whether the package you want to upload will go into Jessie final, and that you are taking a closer look once Jessie is created and the package entered there about the upgradeability. For the time until the suite is available, you can see this as relaxed upload rule.

The same goes for squeeze-backports-sloppy: packages from two suites after Squeeze are acceptable, which turns it into the same relaxed rule as wheezy-backports above. Please also keep in mind that uploads to squeeze-backports-sloppy usually should be accompanied by uploads to wheezy-backports so people are able to upgrade from squeeze-backports-sloppy to wheezy with wheezy-backports.

Thanks

Finally, we want to thank …read more
