I wonder if we should also have an explicit 'unconfined' string to simplify life for people who want to run the container entirely unconfined ? eg avoid them needing the verbose -s static,label=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 > + } else { g_set_error(error, GVIR_SANDBOX_CONFIG_ERROR, 0, _("Unknown > security option '%s'"), tmp); You'll need to re-add the code to detect selinux in configure, since we had got rid of that previously. eg create m4/virt-selinux.m4 containing AC_DEFUN([LIBVIRT_SANDBOX_SELINUX], [ fail=0 old_LIBS=$LIBS old_CFLAGS=$CFLAGS AC_CHECK_HEADER([selinux/selinux.h],[],[fail=1]) AC_CHECK_LIB([selinux], [fgetfilecon],[],[fail=1]) LIBS=$old_LIBS CFLAGS=$old_CFLAGS test $fail = 1 && AC_MSG_ERROR([You must install the libselinux development package in order to compile libvirt-sandbox]) ]) And then add LIBVIRT_SANDBOX_SELINUX to configure.ac, and update libvirt-sandbox/Makefile.am to include SELINUX_CFLAGS and SELINUX_LIBS.
