Hi,
ok. So this is where I create work for people. :-)
Something I've been tossing up for quite some time is a generic
version of this that exposes a ring-buffer of entries back to
userland. For things like this, things like ALQ/KTR, etc, it's all
just a producer-consumer ring based thing. You do

Hi,
So when I did stuff like this back in the day, I also had to deal with
some layers doing not just straight static translations, but things
like dynamic sector remapping for what was effectively software error
correction. Reaching "around" the layers with some mapping from
virtual -> physical d
Well, if the disk itself is throwing errors that early in boot, you've
got a much bigger problem.
Sometimes these things do things with partition schemes and
filesystems behind the scenes. Maybe the CF microcontroller in the
card is confused?

Well, we need geom-in-userland. That would let us do arbitrary
manipulation of partition tables in files and disk images as needed.
It'd also allow for some very cool regression testing.

This is awesome!
Is it just read-only, or does it allow creation/destruction of LDM volumes?

Well, creating a generic geom_compress module shouldn't increase the
size by all that much. It's just a few function pointers that point at
the decompression class. The rest of the format is the same, right?
(ie, how it's broken into chunks, the chunks are separately
compressed, etc.)
This is grea
