From 473c34f895c49bf2bd327ece586d3613cd86c068 Mon Sep 17 00:00:00 2001 From: Emmanuel Dreyfus Date: Sun, 21 Sep 2014 13:57:47 +0200 Subject: Do not hardcode umount(8) path, emulate lazy umount 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.
