I didn't say _you_ did. :-) But a lot of others did.

I don't know, but it doesn't get used a lot and doesn't contain
a lot files. Mainly just a few big files I download off 'da net.

That doesn't sound good.

I saw that one, but it has a slightly different filename than the one on
your CD. I downloaded it anyway, and looked at the RPM header in hopes
of finding the home page, but it contained nothing useful.

I probably won't chance it. Now that I know how severe this can be,
I'll be more careful when downloading big ISO images.

I take it your opinion of ReiserFS hasn't improved? :-)
The thing I don't like about BSware-PRO is being dependent on SGI.
Has SGI released their XFS installer/kernel for RH 8.0? I doubt it.
When a kernel security advisory is issued, I have to wait weeks for SGI
to come out with their patched kernel. Plus updating from from one
release of Redhat to a newer one doesn't work. XFS itself is good, but
adding to BSware is a pain.
Hopefully that'll change in future releases of Redhat. Didn't I
recently read that XFS has been merged into the 2.5.x kernel?
