Subject: bug#18994: Daemon does not preserve supplementary groups of build users
Date: Sat, 08 Nov 2014 15:01:43 +0100 [thread overview]
Message-ID: <87ppcxsse0.fsf@gnu.org> (raw)
Currently, the build environment made by the daemon does not preserve
supplementary groups of the build users.
Thus, even though the standalone Guix system sets /dev/kvm 660, owned by
root:kvm, and adds the build users to the kvm group, build users are
unable to access it.
This can be see with:
(gexp->derivation "foo"
#~(begin (mkdir #$output)(pk (stat:gid (stat "/dev/kvm")) (getgroups))))
The workaround for now is to make /dev/kvm 666.
