<Li> Progressive Unix - like systems have also introduced a concept called supermounting; see, for example, the Linux supermount - ng project . For example, a floppy disk that has been supermounted can be physically removed from the system . Under normal circumstances, the disk should have been synchronized and then unmounted before its removal . Provided synchronization has occurred, a different disk can be inserted into the drive . The system automatically notices that the disk has changed and updates the mount point contents to reflect the new medium . </Li> <Li> An automounter will automatically mount a file system when a reference is made to the directory atop which it should be mounted . This is usually used for file systems on network servers, rather than relying on events such as the insertion of media, as would be appropriate for removable media . </Li> <P> Linux supports numerous file systems, but common choices for the system disk on a block device include the ext * family (ext2, ext3 and ext4), XFS, JFS, ReiserFS and btrfs . For raw flash without a flash translation layer (FTL) or Memory Technology Device (MTD), there are UBIFS, JFFS2 and YAFFS, among others . SquashFS is a common compressed read - only file system . </P> <P> Solaris in earlier releases defaulted to (non-journaled or non-logging) UFS for bootable and supplementary file systems . Solaris defaulted to, supported, and extended UFS . </P>
