If you wish to backup multiple filesystems, you can explicitly
list each filesystem you want saved. Otherwise, if you set the onefs option
to {\bf no}, Bacula will backup all mounted file systems (i.e. traverse mount
explicitly name each filesystem you want backed up. Explicitly naming the
filesystems you want backed up avoids the possibility of getting into a
infinite loop recursing filesystems. Another possibility is to

+ second File directive shown above. In effect, the warning is bogus,
+ but it is supplied to alert you to possible omissions from your FileSet. In
