>Organization:
>Environment:
NetBSD armv7 7.1 NetBSD 7.1 (RPI2.201703111743Z) evbarm
>Description:
When enabling LVM in the given environment, the cgd module is supposed to be automatically loaded. This fails because of missing dependencies. There was a fix for this in current and netbsd-8. Anyway, it would be nice if this can be pulled up to the netbsd-7 and netbsd-7-1 branches too.

>How-To-Repeat:
- on NetBSD armv7 7.1 NetBSD 7.1 (RPI2.201703111743Z) evbarm, enable lvm in rc.conf
- reboot
