} So much fail on my part.
} # which lvm
} Confused at the section in https://www.netbsd.org/docs/guide/en/chap-lvm.html:
} 17.4. Configure LVM on a NetBSD system
} For using LVM you have to install lvm2tools and libdevmapper to NetBSD
} system. These tools and libraries are not enabled as default.
} To enable the build of LVM tools, set "MKLVM=yes" in the /etc/mk.conf
} or "MAKECONF" file.
Not for long it won't. I'm updating it right now.
} ...I take it that this is no longer required in current release. For
} my needs I think I just need to compile a custom kernel and done.
