[gentoo-user] using lvm without a partition of type linux LVM

The lvm handbook addendum is no longer and we are instead to use
the software raid + lvm2 quick install guide.

That guide makes a few partitions of type linux raid and then puts lvm
on a mirrored set (more is done).

I wasn't using raid so skipped that step and wound up with 
one partition as a pv in my single vg and created several lvs in that
vg.

So far so good.  But I realized that the single partition that I used
was of type linux instead of linux lvm as I had always done when
following the lvm handbook addendum.

So what, I've made plenty of mistakes before, and will surely make
plenty more later.

But the resulting system works perfectly!

If this is risky; I can reinstall.  But I wonder if any action is
necessary.

What do you think?
