So a simple test like this (similar as what can be seen used in the code) reveals the problem with all /sys sub-mounts dissapearing: mount | grep /sys mkdir /tmp/test mount --rbind /sys /tmp/test mount | grep /sys umount --lazy --recursive /tmp/test mount | grep /sys (The same problem doesn't seem to occur without the --lazy flag, but then mount errors out after doing most of the job.)
