SansaLinux is a port of iPodLinux for the Sandisk Sansa e200 MP3player series. It is useable only with the original e200 series, but not with the V2 models.
Sansalinux comes with a bootloader, a 2.4 Linux-kernel, a modified podzilla2 and some podzilla-plugins. It needs no repartitioning of the Sansa-flash. It runs directly from an ext2 loop-filesystem which is stored on the FAT-filesystem. SansaLinux is using modified versions of Rockbox drivers and the Rockbox Bootloader.
