@cindex snapshot files, fixing device numbers
Sometimes device numbers can change after upgrading your kernel
-version or recofiguring the harvare. Reportedly this is the case with
+version or reconfiguring the hardware. Reportedly this is the case with
some newer @i{Linux} kernels, when using @acronym{LVM}. In majority of
