- This is the de facto standard Linux file system (method to organize
- files on a storage device) for hard disks.
-
- You want to say Y here, unless you intend to use Linux exclusively
- from inside a DOS partition using the UMSDOS file system. The
- advantage of the latter is that you can get away without
- repartitioning your hard drive (which often implies backing
- everything up and restoring afterwards); the disadvantage is that
- Linux becomes susceptible to DOS viruses and that UMSDOS is somewhat
- slower than ext2fs. Even if you want to run Linux in this fashion,
- it might be a good idea to have ext2fs around: it enables you to
- read more floppy disks and facilitates the transition to a *real*
- Linux partition later. Another (rare) case which doesn't require
- ext2fs is a diskless Linux box which mounts all files over the
- network using NFS (in this case it's sufficient to say Y to "NFS
- file system support" below). Saying Y here will enlarge your kernel
- by about 44 KB.
-
- The Ext2fs-Undeletion mini-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>, gives information about
- how to retrieve deleted files on ext2fs file systems.
-
- To change the behavior of ext2 file systems, you can use the tune2fs
- utility ("man tune2fs"). To modify attributes of files and
- directories on ext2 file systems, use chattr ("man chattr").
-
- Ext2fs partitions can be read from within DOS using the ext2tool
- command line tool package (available from
- <ftp://ibiblio.org/pub/Linux/system/filesystems/ext2/>) and from
- within Windows NT using the ext2nt command line tool package from
- <ftp://ibiblio.org/pub/Linux/utils/dos/>. Explore2fs is a
- graphical explorer for ext2fs partitions which runs on Windows 95
- and Windows NT and includes experimental write support; it is
- available from
- <http://jnewbigin-pc.it.swin.edu.au/Linux/Explore2fs.htm>.
