NLS char set and fsck

Apologies if this has been discussed. I don't want anyone else to get
burned, and I just noticed that my linux-kernel subscription was gone.

Recently, mount has been telling me it can't find the NLS code page
for my /msdos partition. I ignored the problem, but apparently that
was a bad idea. I thought scandisk had gone bananas, until I realized
that a) I haven't run scandisk or even booted into Win/DOS for a week or
two, and b) scandisk doesn't use names like FSCK0000.BIN.

Anyway, it blew away windows and a lot of other directories/files by
renaming them to the same names (apparently), all in the automatic
fsck mounting procedure. I am not sure when this started, but the
windows directory worked from wine until sometime this past week.
Note that the directory is always mounted read only, and the kernel
has not changed recently - fsck is dated as April 97, but
/sbin/dosfsck is Jan 9, so it must have been what changed.

I think the kernel/fsck should be careful about mounting a filesystem
or checking one if it doesn't have the code pages. What exactly is
the current policy? I think the behavior I am describing is bad under
any circumstances.

Anyway, I've taken win/dos out of mounting/fstab for now, and am
upgrading/recompiling to get rid of this behavior by adding more
codepages as soon as I can get a compile to finish.
A computer lets you make more mistakes faster than any other
invention, with the possible exceptions of handguns and Tequilla.
