Could the persions please not appear the forum any more? as they are only capable of saying "man xyz", which are not helpful at all, since everybody able to use linux are able to use man.
frankly, if you really know how to use man, u will not ask this question here at all. i ask u to man fstab is because u can learn by yourself. which is more important.
sigh. people are eager to get answers, but ignore the ability of getting answers.
