autofs-5.1.4 - set bind mount as propagation slave
When using a multi-mount with mount targets that are on the
local machine and resulting bind mounts are made to a file
system that is mount propagation shared (such as the root
file system on systemd managed systems) the autofs offset
mount triggers made within the bind mount will be propagated
back to the target file system.
When this happens the target of the offset (the unwanted
propagated mount) is itself an autofs trigger mount and
accessing the path results in a deadlock.
In order for these multi-mounts to function properly in this
case bind mounts that contain mount triggers must be set to
propagation slave or private so the backward propagation
doesn't occur.
