/sys/class/dmi/id/chassis_type
Of course, that value comes from the firmware. You want to trust firmware
vendors?
This tends to be a better source for information like this:
/sys/firmware/acpi/pm_profile
And since Windows cares for this bit it even tends to be reliable to
some level.
hostnamed exposes a "Chassis" property on the bus (and hostnamectl will
show you this), which looks for both of this files and allows users to
override this file.
That said, it sounds like a horrible hack to make use of this for
turning on/off LVM.
Quite frankly, I am pretty sure LVM has no place on non-servers, and should
not be offered by the desktop installer.
