[libvirt] [sandbox 1/2] Pass debug and verbose values to init

libvirt-sandbox-init-common is expecting -d and -v parameters to set it in debug or verbose mode... but those will never be passed by the launcher program. Writing the core.debug and core.verbose parameters in the sandbox configuration makes those values actually usable from the init. --- bin/virt-sandbox.c | 3 ++ libvirt-sandbox/libvirt-sandbox-config.c | 75 +++++++++++++++++++++++++++ libvirt-sandbox/libvirt-sandbox-config.h | 6 +++ libvirt-sandbox/libvirt-sandbox-init-common.c | 3 ++ libvirt-sandbox/libvirt-sandbox.sym | 4 ++ 5 files changed, 91 insertions(+) diff --git a/bin/virt-sandbox.c b/bin/virt-sandbox.c index 3058013..6032562 100644 --- a/bin/virt-sandbox.c +++ b/bin/virt-sandbox.c @@ -273,6 +273,9 @@ int main(int argc, char **argv) { if (shell) gvir_sandbox_config_set_shell(cfg, TRUE);
