Ah, wonderful!  2.4 kernel support has been _added_ to NTFS-3g's
"FUSE-lite" since I last looked!

Nice to see 2.4 kernel support is still an active priority ;-)

Thanks for the info, it's really useful.  I would never have thought
to check for 2.4 support being added back, since an earlier
announcement said it was no longer supported.

(Btw, The NTFS-3g release notes, on it's decision to replace the FUSE
userspace libs (which is what makes it work with 2.4 kernels too),
suggest there may be serious problems in the standard FUSE libs,
especially on small devices.  It doesn't bother me, as I only need
NTFS-3g, not other FUSE capabilities, but perhaps FUSE developers
would like to take a look at those problems.)

Thanks again,
