My grml-debootstrap configuration is here: https://github.com/adrelanos/minimal-grml-debootstrap-test
(I think it's quite useful to have a single script/configuration around for producing minimal instructions on how to produce that bug.)
grml-debootstrap keeps failing for me. umount: /mnt/debootstrap.23035: device is busy
I guess it could be because this bug in kpartx: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=734794
umount: /mnt/debootstrap.23035: device is busy
I just double checked this. It also happens in a freshly installed Debian Jessie VM.
Could you check please, if you can confirm, that grml-debootstrap is currently broken after applying all updates in Debian Jessie?
Apart from the kpartx bug, I am quite sure another bug related causing "device is busy" has been introduced in in linux 3.12-2-686-pae. The older 3.11-2-686-pae kernel seems unaffected.
reliably mount/unmount with 3.11-2-686-pae, but not with 3.12-2-686-pae. I couldn't make myself a bug report without "you need to download that/an image".
I just tried to reproduce this issue, it seems to work for me on Debian/wheezy as well as on Debian/jessie (as of today with linux-image-3.12-1-amd64 v3.12.9-1 and kpartx 0.4.9+git0.9c3c5172-1). [I just didn't use your custom config and package list and used amd64 instead, but I used the command line from your script, ftr.]
Maybe check whether the updates included in the current linux kernel package 3.12.9-1 fixes the issue for you?
Yes, after updating the issue was gone.
Thank you for your help!
Cheers, Patrick
