Subject: propagate semantic changes to NEED_ROOT, NEED_ROOT_OR_IS_DEVICE
X-Git-Tag: 1.0.67~31
X-Git-Url: http://git.annexia.org/?a=commitdiff_plain;h=4a5e13f15734aa7363e605f716ad6e29c67475c5;p=libguestfs.git

propagate semantic changes to NEED_ROOT, NEED_ROOT_OR_IS_DEVICE

changing IS_DEVICE semantics leads to changing semantics of
NEED_ROOT_OR_IS_DEVICE and NEED_ROOT, too.
* daemon/daemon.h: Update definitions.
