Netkit - problem

Witam,
Mam problem z instalacją Netkita. Po uruchomieniu skryptu sprawdzającego pojawia mi się takie coś:

*** Warning: You appear to be running Netkit on a filesystem ()
that does not support sparse files. This may result in dramatic performance
loss and disk space consumption. It is strongly advised to run Netkit
on a filesystem that supports sparse files (e.g., extX, NTFS, ReiserFS do;
FAT32 does not).

>  Checking whether 32-bit executables can run... passed.

[WARNING] Some configuration settings should be changed.
          You may also ignore this message, but doing so may result in Netkit
          not working properly on your system.

Co robić? :D
