You mean using async? I don't usually use async. I did used async a few times today experimenting with mount /home with no intention to use async later.
Fortunately crash have not happened during these experiments. Actually noasync is redundant for this script, because I don't use async in fstab. Command, for me, is going to remount /home from normal: normal metadata sync data async to fully synced: sync metadata sync data sync async was only today for experimenting, but I like redundancy so probably noasync will stay. I don't see anything else which can be dangerous, but maybe I am missing something.
