Since 2.36, libmount unconditionally use O_PATH. I think the right way moving forward is to disable mount on prefix. But that will affect glib and should be done at once.
(In reply to Benda Xu from comment #1) > I think the right way moving forward is to disable mount on prefix. I'm not a prefix user, but I think it would make sense to disable it only for platforms that do not support O_PATH.
interesting, paths.h is provided by glibc. Somerthing tells me util-linux does some detection of some sort and doesn't consider the fact of a glibc not provided by the host
I doubt anyone still needs a prefix on kernel 2.6.32, so closing as obsolete.
