If you do not have USE=lvm somehow globally enabled, this means +you will lose LVM2 (but not device-mapper!) functionality, so enable it in your +config if your boot configuration depends on it or if you depend on any of the +lvm2-* daemons. + +Furthermore, we have considered other default enabled USE flags too, and have +come to the conclusion that USE=+thin makes even less sense than USE=+lvm. +Thin-provisioned LVM volumes are an important use case in certain VM hosting +scenarios, but unlikely to be relevant for the large majority of Gentoo users. + +In summary: +- Enable USE="lvm" if you use lvm2 (but not needed for device-mapper) as described above. +- Enable USE="lvm thin" if you use thin as described above. +- If you don't know what LVM2 is, you don't need to take any action. -- cgit v1.2.3
