-a All filesystems set auto in /etc/fstab [of the given fstypes]
-F Fork a process for each device and NFS servers in parallel.
NFS timeouts will be independent, i.e. if one server or device is unavailable it won't hold up the other mounts.
mounts are done in undefined order.
do not use this option if you want to mount both /usr and /usr/spool.
-r read-only
-w read/write.
-ffake the actual mount. useful in conjunction with the -v flag to determine what the mount is trying to do. It can also be used to add entries for devices that were mounted earlier with -n .
-n no writing to /etc/mtab.
Useful when /etc/fstab is on a read-only file system.
-s sloppy mount options don't cause exit
-L label the partition specified label.
-U uuidthe partition that has the specified uuid
-o other :
  • async I/O to the file system should be done asynchronously.
  • sync
