From the man page for ps:
To perform the device number to name mapping ps maintains
a file called "/etc/psdevtab" (updated whenever "/dev"
becomes newer and permissions allow update). If permis-
sions do not allow update, every invokation of ps requires
a stat(2) of every file in the "/dev" directory. If
"/dev" changes often on your system you should run ps as
root often. ;-) I may add a fallback file under $HOME
under force of popular demand.
