CentOS - Aug 2005 - Starting a process at a specified nice value.

I wonder if someone could point me to the appropriate docs for my question? If 
I would like to cause my system to always start 'smbd' processes at
priority
7 for example, how would I go about doing that. 

I'm assuming there's a better way than running a cronjob every minute to
renice existing processes. 

I'd appreciate some help pointing me in the right direction.

Thanks.

smbd is started by /etc/init.d/smb

Find where that script starts smbd, and prefix smb with something like
this:
nice -n 7 

This isn't a particularly elegant solution, but it will work.

You should note that upgrades to Samba may overwrite /etc/init.d/smb, so
you may need to make this change again after an upgrade.
