What are the options for mounting file systems?

rw (read-write) - read and write. ro (read-only) - read only. auto - automatic detection of the filesystem type. noauto - requires explicit mounting. user - allows a regular user to mount the device. nouser - only root can mount the device. exec - allows execution of executable files on partitions. noexec - prohibits execution of executable files. sync - synchronous data writing to disk. async - asynchronous data writing to disk. defaults - default set of options (usually rw, suid, dev, exec, auto, nouser, async). dev - interpret block devices on the filesystem. nodev - do not interpret block devices. suid - handle SUID and SGID bits. nosuid - ignore SUID and SGID bits. remount - remount an already mounted filesystem with new options. bind - mount a subtree of the filesystem to another location. loop - mount a file as a block device.

Example entry in /etc/fstab:

#/dev/sda1 /mnt/data ext4 defaults,noatime 0 2
