This commit fixes an issue with reading and writing files.
File.open is used which means that a file will remain open
unless explicilty closed or the program exit. This doesn't work
for an NFS mount as the scripts try to "rm -rf" when the file
is still open. This commit fixes that by replacing all .opens
with .reads
