I thought the fix was going to occur as part of the install. Below is the original fstab after install:
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a device; this may
# be used with UUID= as a more robust way to name devices that works even if
# disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>

Below is the fstab after the sed is run:

So it looks like the sed didn’t work??
