boot error (?)

[Marco Calviani <mirtux@studenti.fisica.unifi.it>]

Hi,
 i've got an error (maybe a warning) during the boot up process, as 
written in /var/log/boot:

Cleaning /tmpfind: warning: you have specified the -maxdepth option 
after a non-option argument -perm, but options are not positi
onal (-maxdepth affects tests specified before it as well as those 
specified after it).  Please specify options before other argumentsboo

find: warning: you have specified the -depth option after a non-option 
argument !, but options are not positional (-depth affects
tests specified before it as well as those specified after it).  Please 
specify options before other arguments.

find: warning: you have specified the -depth option after a non-option 
argument !, but options are not positional (-depth affects

specify options before other arguments.

What might be the cause?

Thanks,
MC
