 mtd-Device benötigt. Da ubifs ohnehin in allen Bereichen deutliche Vorteile
 gegenüber jffs2 hat, wird UBIGLUEBI in der Regel nicht mehr benötigt.

+\begin{itemize}
+\item something like a partition in common systems
+\item but more flexible
+\item ubi exchanges eraseblocks between volumes (for bad block handling,
+wear-leveling)
+\item non-linear mapping of physical eraseblocks (peb) to logical eraseblocks
+(leb)
+\item e.g. a volume out of 3 blocks could use peb 813, 28, 1017
