:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that systemd-logind should be allowed sys_tty_config access on the  <Sconosciuto> by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:Do
:allow this access for now by executing:
:# grep systemd-logind /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Daniel Walsh 2012-01-31 19:56:52 UTC
systemd guys, does systemd-logind actually need to configure a tty?

/* Allow configuration of tty devices */
/* Allow vhangup() of tty */

#define CAP_SYS_TTY_CONFIG   26

Comment 2 Michal Schmidt 2012-02-01 08:17:58 UTC
To implement "systemd-loginctl activate ..." systemd-logind wants to be able to switch VTs (VT_ACTIVATE ioctl) without being their owner. The CAP_SYS_TTY_CONFIG capability allows it to do that.
