no capisco come mai all'avvio del pc che uso cone nfs di rete
(366mhz - 256mb ram  40+30 gb hdd)
quando ottengo questi errori impiega molto tempo a proseguire
l'esecuzione del boot:

------
Exporting directories for NFS kernel daemon...exportfs: No host name
given with /mnt/40GB/dati (rw,no_root_squash), suggest
*(rw,no_root_squash) to avoid warning
exportfs: /etc/exports [3]: No 'sync' or 'async' option specified for
export ":/mnt/40GB/dati".
  Assuming default behaviour ('sync').
  NOTE: this default has changed from previous versions
exportfs: No host name given with /mnt/localapt (rw,no_root_squash),
suggest *(rw,no_root_squash) to avoid warning
exportfs: /etc/exports [4]: No 'sync' or 'async' option specified for
export ":/mnt/localapt".
  Assuming default behaviour ('sync').
  NOTE: this default has changed from previous versions
done.

addirittura quando monto da un altro pc la condivisione, il processo
risulta lento, ed a volte non va a buon fine!

il mio /etc/exports
# /etc/exports: the access control list for filesystems which may be
exported
#               to NFS clients.  See exports(5).
/mnt/40GB/dati (rw,no_root_squash)
/mnt/localapt (rw,no_root_squash)


dipende anche da quanto c'e nelle directory montate? no credo.....

grazie
