This will not work for what the OP wants to do - which is change many entries within /etc/vfstab - you're just passing some static string to the sed. Also, the backslashed escaped slashes, whilst legal syntax, make the sed expression hard to read - replacing the delimiters with "!" (or anything else) increases the readability of the expression.
