I'm using a two-partition setup with ubuntu (one partition for the system, one for my home directories). Until now I had an ext3 formatted home partition, which I'm currently trying to migrate to an encrypted ext4 partition.
However, when copying the files the system is bugging me with errors, complaining that filenames are too long. As far as I could find out using wikipedia filename length is 255 bytes for ext3 and 256 bytes for ext4. So where's the problem, and how can I solve it?
