#!/bin/bash # This is a helper script which is called by container-storage-setup.sh (d-s-s). # This script helps in providing synchronization primitives to d-s-s so that # d-s-s can determine whether deferred deletion is supported by the underlying # kernel or not. # $1 is named FIFO pipe. # This helper script will write to $1 to signal d-s-s that unshare has been completed successfully. # $2 is another named FIFO pipe. # This helper script will read from $2. The write for this pipe would come from d-s-s to indicate # that helper script can terminate now. # $3 is absolute path to a temp dir which child will bind mount. Parent will # later try to remove this dir. if ! mount -o bind $3 $3; then echo "stop" > $1 exit 1 fi echo "start" > $1 read -t 10 n <>$2
