Do not hardcode umount(8) path, emulate lazy umount 2014-10-03T14:57:47+00:00 Emmanuel Dreyfus manu@netbsd.org 2014-09-21T11:57:47+00:00 473c34f895c49bf2bd327ece586d3613cd86c068 1) Use a system-dependent macro for umount(8) location instead of relying on $PATH to find it, for security and portability sake. 2) Introduce gf_umount_lazy() to replace umount -l (-l for lazy) invocations, which is only supported on Linux; On Linux behavior in unchanged. On other systems, we fork an external process (umountd) that will take care of periodically attempt to unmount, and optionally rmdir.
