untar'ing an archive with /dev files crashes qrexec

[Holger Levsen]

Hi,

so, I've started to use Qubes for real, and I can say I'm already quite very
happy how nicely it works (VM seperation etc) and also how "easy" it is to use.
Kudos & thanks to all involved making this happen!

That said, I will now write a serious of mails with some small issues I'm having.

So, I copied my data into one big VM (a mistake…) and am now creating tar-balls
which I'm qvm-copy-to-vm'ing to other VMs. One of these tarballs contained a
chroot for a live-system. Upon untar'ing mknod was complaining that it couldnt
create those files in ./dev and appearantly that crashed qrexec on the VM!

(This is on Qubes 3.2 with a 4.8er kernel, the VM runs Debian 8.)

After reproducing this 3 times I've excluded that old chroot from that tarball,
after which I could untar it without problems…

Is this a known issue or should I create one on github for this? Is it
avoidable at all?
