| H A D | vmimage.subr | diff 963412283a1752b3b6f67bb86940c9d166a59e67 Mon Mar 30 10:33:19 CEST 2015 Colin Percival <cperciva@FreeBSD.org> Clean up filesystem unmounting in vmimage builds:
* Remove vm_umount_base function which is currently unused.
* Add umount_loop function which loops attempting to unmount one filesystem.
* Replace calls to umount with calls to umount_loop.
* Don't attempt to unmount ${DESTDIR}/dev if it isn't mounted.
The looping is necessary because sometimes umount fails due to filesystems
being busy. The most common cause of such busyness is periodic(8) jobs
running `find / ...`.
