Subject: Here is LVM support for OpenWRT. It introduces 3 new packages: -
 kmod-dm for the device mapper kernel module. - kmod-libdevmapper for the
 device-mapper library. - kmod-lvm2 for the lvm tool. Note that it currently
 does not create the symlinks for all the lvm tools, so you have to use lvm
 pvs rather than just pvs. Thanks Stefan Monnier
