Furthermore, since the +default was changed in udev 152 from 'add' to 'change', the command +needs to explicity name 'add' as the action. + +Signed-off-by: Tom Zanussi <tom.zanussi@intel.com> +--- + meta/recipes-core/initrdscripts/files/init-live.sh | 1 + + 1 files changed, 1 insertions(+), 0 deletions(-) + +diff --git a/meta/recipes-core/initrdscripts/files/init-live.sh b/meta/recipes-core/initrdscripts/files/init-live.sh +index c96b1f4..f3e5145 100644 +--- a/init-live.sh ++++ b/init-live.sh +@@ -11,6 +11,7 @@ early_setup() { + mount -t proc proc /proc + mount -t sysfs sysfs /sys + udevd --daemon ++ /sbin/udevadm trigger --action=add + } + + read_args() { +-- +1.7.0.4 + |
