+define Package/libdevmapper/description
+  The Linux Kernel Device Mapper is the LVM (Linux Logical Volume Management)
+  Team\'s implementation of a minimalistic kernel-space driver that handles
+  volume management, while keeping knowledge of the underlying device layout
+  in user-space.  This makes it useful for not only LVM, but EVMS, software
+  raid, and other drivers that create "virtual" block devices.
+  .
+  This package contains the (user-space) shared library for accessing the
+  device-mapper; it allows usage of the device-mapper through a clean,
+  consistent interface (as opposed to through kernel ioctls).

+define Package/lvm2/description
+  This is LVM2, the rewrite of The Linux Logical Volume Manager.  LVM
+  supports enterprise level volume management of disk and disk subsystems
+  by grouping arbitrary disks into volume groups. The total capacity of
+  volume groups can be allocated to logical volumes, which are accessed as
+  regular block devices.

+# I got problems building with readline, so I originally just disabled it.
+# I've since added patch 100-readline-link which fixes the problem instead.
+# CONFIGURE_ARGS += --disable-readline
+
+# Apparently we have problems when "read"ing using O_DIRECT, maybe because
+# of uClibc.  More specifically, with O_DIRECT lvm becomes erratic, showing
+# non-deterministic behavior: `lvs', `pvs' and friends can return anything
+# from empty lists, to completely correct result, as well as checksum errors,
+# complaints about missing volume groups, ... each run of the command can
+# return something different.  The "root" of the problem is (maybe among
+# other places) in the "_io" function in dev-io.c, where calls to the "read"
+# function often return garbage, although not always.  There's nothing
+# obviously wrong with the dev-io.c code, so the bug may just as well be in
+# uClibc or in the kernel (it appeared on the MIPS platform and could be
+# related to cache coherency issues).
+# Debian Lenny's lvm2 also disables O_DIRECT on "arm armeb hppa mips mipsel".
