[buildd-tools-devel] Bug#559019: schroot: copyfiles doesn't support device files

[Raphaël Hertzog]

Package: schroot
Version: 1.2.3-1+b1
Severity: normal

I run virtualbox-ose in a 64 bit chroot managed by schroot because I run
a 64 bit kernel and want to run 64 bit virtual machine but my machine is
setup as i386. For virtualbox to work properly I need /dev/vboxdrv and
/dev/vboxnetctl in the chroot and it needs to be in sync with the host
(a one-time copy is not enough due to dynamic allocation of device numbers
by the kernel).

So I wanted to put /dev/vboxdrv and /dev/vboxnetctl in
/etc/schroot/copyfiles-defaults but it leads to error message like:
/usr/bin/md5sum: /dev/vboxdrv: Invalid argument
/usr/bin/md5sum: /var/lib/schroot/mount/sid-amd64-7deb8402-75d4-4a90-9f24-c38159f6f9b9/dev/vboxdrv: Invalid argument

when the file already exists and to failures when it doesn't exist:
$ LANG=C schroot -c sid-amd64 -p
/usr/bin/md5sum: /dev/vboxdrv: Invalid argument
cp: reading `/dev/vboxdrv': Invalid argument
E: sid-amd64-ee46539c-eb7a-4cef-944f-dbd372b93442: Chroot setup failed: stage=setup-start

You want to compute md5sum only for real files (or symlinks to real files), and
use "cp -a" on other kinds of files.

Cheers,
