Hi, thank you very much for all the input. To clearify things a little: Status quo: System with ext4 and no extended attributes. Where I want to be: The same system with extended attributes. Way to go: No reformatting and mkfs and all that things. Only kernel reconfiguring / recompiling / rebooting and emerging some tools. Possible? Best regards, mcc
