In the current version of initscripts, in order to get the number of
processors in the system and to print that on the login, the rc.local
makes something like
grep -cl <some regular expression> <somefile>
this should be fixed as
egrep -c <the same reg. ex. > <the same file>
The egrep is used to count the number of processor, with the -c option.
I can be more precise if necessary.
This is fixed in the various errata initscripts.
