To be picky, they do get updated, if SC detects you have made changes to
the them while booted to related OS.

All I'm saying, is you can't know. LVM places a special signature in some
reserved bytes of the MBR. In addition, as I understand it, LVM uses the
last sector of the boot manager partition to keep track of it's settings
and the drive letter assignements. Daniela and Jan are the experts on
this and we should as them. A problem occurs if SC does not preserve this
information and some other OS decides to use the same areas. I'm not
saying it's going to happen. I'm only saying it needs to be tested to
ensure nothing dies.

To be absolutely safe, SC would need to save and restore these sectors
when switching from and to a LVM aware OS.
