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
