Nope. Not at all. Just wanted to know the difference, which you explained

True.

Dedicated partition for the kernel backups.

If /altroot isn't particularly used in rh, I could clean it, copy
/lib/modules to it, and change the mounting so it mounts under
/lib/modules, I suppose. But it sounds like just dedicating a full
gigabyte (or more on really large drives) to the root partition would be
just as effective or more so, next time around.

That's what I've done in the past -- watched the applet, updated in a
virtual terminal with yum. I was just lazy enough this time to update
directly from the applet.

So, for next time around, I should also give /var 4G or more, I think.
And for the present, I should avoid waiting so long between updates, or
if I do, update X and the fonts first, and then update Open Office after,
cleaning the cache between.

(Or start getting rid of apps I don't use.)

Thanks again.
