+ 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.linuxdoc.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

^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I seem to recall if you say Y to ext2 and Y to ext3 and your root is on ext3
then it's likely to be mounted as ext2 unless you set rootfstype=...
The ext3 help comment also warns you should set it to Y, so people with
root ext3 are likely to get a surprise if they follow both help. Would it
be better to say something like "if your root partition is extX you almost
certainly want to say Y here"? Or warn about the rootfstype issue maybe?

Was thinking of the "ext3 clings to you like flypaper" thread of a couple
weeks ago, only backwards... -ESLEEPY
Anyway, I have seen instances where root got mounted ext2 instead of ext3
(faulty initrd or whatever it was) - just wondered if the help should really
push people to unreservedly say Y to ext2 if their root is really ext3...

Should be safest for most people .. those that have experience will
anyhow know to only compile in ext3 support, and ext2 as module (if
you ever fsck floppy/whatever as ext2).

Hi Martin,
I'm having trouble decoding...
What is it that "should be safest for most people"?
Are you suggesting any changes here?
And some of us don't use fs modules, just build what we need into the
kernel. Do you know of any problems with doing this (related to
ext2/ext3 for example)?
Thanks,
~Randy

I was just saying that recommending it (ext2) compiled into the kernel
and not a module should be the safe route for newbies to kernel
compiles.
Those of us that have build a few to feel comfortable with it, will know
to compile the fs of our / partition into the kernel.
Except if ext2 is not the most commonly used fs anymore. I guess a
'cool' feature could be if the make system could 'detect' what your
current root is and warn if you do not have that compiled into your
kernel, but I do not know the limitations of it (the make system).
Then on the other hand, would above be confusing if its a kernel
compiled for another box ?
Regards,

Yes, I'd say so, although the message could say something like:
Kernel does not include a filesystem for / on this computer.
And would it also have to check the capabilities of what's in the
initrd? (not that I'm advocating any of this)

To me that sounds like a feature for the bootloader
config tool. That is the first time you have a firm
kernel to rootfs connection.

Well... the only time *I*'ve screwed it up was building with ext3 only,
having all ext3 filesystems on the disk, and watching Bad And Ugly things
happen when the ext2-format initrd tried to mount...
