I bought a Lenovo P70 laptop back in 2018? and all hardware was 
supported by the kernel. This wasn't a cheap laptop though, it set me 
back about $2400.

 Does anybody have this printer?

 Is there a driver in overlay to setup this printer?

 Installing those drivers from rpm and cupswrapper is tiring.

I have a different brother printer but I used an ebuild from
brother-overlay
 as a
template. The closest to your printer would likely be
brother-hll8350cdw-bin-1.1.2-r1.ebuild
.
Rename to brother-hl6200dw-bin-1.1.2-r1.ebuild. Change the parts of
SRC_URI to match the download URI used to download the driver(s)
from the Brother website. Change instances of "hll8350cdw" to
"hll6200dw".


This is a good idea. I've the files (modified them):
brother-hl6200dw-bin-1.1.2-r1.ebuild and metadata.xml

My only question is which directory to put them in? I think:
/usr/local/portage/(something)


That's described in
. In short:
eselect repository create 



I just tired generic brother printer and it works perfectly.
emerge --ask net-print/brother-genml1-bin
 
No need to complicate installation of specific driver.

/dev/mapper/vg0-usr and /dev/dm-1 are the same device, so nothing is
actually wrong, this is more a cosmetic issue. You are mounting the
correct device, it is just showing as a different name.

I suspect the initramfs here, what does the fstab inside that look like?

How are you creating the initramfs? Genkernel, dracut, home brewed?

If it isn't, then there's something wrong. You should be using 
/dev/mapper/..., which should be a link to whatever device is underlying 
it. /dev/dm-1 will be whatever devicemapper brought up as the first 
device it found.
