For instance, they compile it with the wrong options set, their boot scripts are wrong, they just shovel software onto the CD. Use SuSE, and trust me, ReiserFS will boot faster than ext2. Actually, I am curious as to exactly how they manage to make ReiserFS boot longer than ext2. Do they run fsck or what? Hans > etc, Until I switched to ext2 on all those. Now the boot time is...
