Zbigniew Jędrzejewski-Szmek	5a664ca10f	rules: add a rule to set /dev/kvm access mode and ownership (#5597) ... Kernel default mode is 0600, but distributions change it to group kvm, mode either 0660 (e.g. Debian) or 0666 (e.g. Fedora). Both approaches have valid reasons (a stricter mode limits exposure to bugs in the kvm subsystem, a looser mode makes libvirt and other virtualization mechanisms work out of the box for unprivileged users over ssh). In Fedora the qemu package carries the relevant rule, but it's nicer to have it in systemd, so that the permissions are not dependent on the qemu package being installed. Use of packaged qemu binaries is not required to make use of /dev/kvm, e.g. it's possible to use a self-compiled qemu or some alternative. https://bugzilla.redhat.com/show_bug.cgi?id=1431876 To accomodate both approaches, add a rule to set the mode in 50-udev-default.rules, but allow the mode to be overridden with a --with-dev-kvm-mode configure rule. The default is 0660, as the (slightly) more secure option.	2017-03-27 12:34:24 +02:00
Martin Pitt	61f32bff61	tmpfiles: drop /run/lock/lockdev ... Hardly any software uses that any more, and better locking mechanisms like flock() have been available for many years. Also drop the corresponding "lock" group from sysusers.d/basic.conf.in, as nothing else is using this.	2016-02-01 12:16:24 +01:00

Lennart Poettering	94655a1670	sysusers: split up default sysusers snippet ... This ways, distributions have an easier way to replace the OS specific generic groups/users while keeping systemd's own.	2014-06-29 22:27:07 +02:00
