Bug#1140336: udev: fchownat() of /dev/kvm failed: Operation not permitted

[Benjamin Drung]

Package: udev
Version: 261~rc4-1
Severity: normal
X-Debbugs-Cc: bdrung at debian.org

Dear Maintainer,

I am using sbuild with the unshare backend and this config for autopkgtest:

$autopkgtest_opts = ['--', 'unshare', '--release', '%r', '--arch', '%a', '-b', '/dev/kvm', '/dev/kvm'];

Running sbuild --run-autopkgtest on the dracut source code started to
fail during package installation:

Setting up udev (261~rc4-1) ...
Creating group 'input' with GID 995.
Creating group 'sgx' with GID 994.
Creating group 'clock' with GID 993.
Creating group 'kvm' with GID 992.
Creating group 'render' with GID 991.
fchownat() of /dev/kvm failed: Operation not permitted
dpkg: error processing package udev (--configure):
 old udev package postinst maintainer script subprocess failed with exit status 73
