ps x is fat!


Hello folks-

My first post on linuxq's.com. Looks like a pretty popular site.

I am running a fairly new install of Slack 12 and am pretty sure I have a lot of stuff running that I don't need. For examply, I have jfs and xfs 'stuff' running. All my partitions are reiser. This is my home pc running DSL (no, not damn small but internet DSL) via ethernet (fiber). The only 'extra' things I will do is serve some files via ftp.

I've found several references to deamons, services, etc but cannot find everything listed to know whether or not I need it. My PC is a PIII500 so I don't want anything running I don't need.

Below is output from ps x:

It seems that everything starting with a 'k' are processes supporting the kernel, and they are normal. You are correct, the jfs and xfs stuff probably shouldn't be running. Other than that everything seems to be ok.

I should note that, excepting the X apps (seamonkey, rxvt etc), most of those show up for me to, but not in a "ps x". All the kernel helpers show up in a "ps -A", but not a "ps x". Weird, but I think that yours is the "correct" behavior.

I've looked in all my rc files and xfs/jfs stuff isn't listed anywhere so I'm really shaking my head there. Shouldn't anything running at boot be in one of those files?

Anything between [] in the output of ps is a kernel thread. In the case of your xfs/jfs processes, they are there because your kernel was compiled with support for the xfs/jfs file systems. The only way to get rid of them, is to recompile your kernel without support for those file systems.

They are not started by your init scripts. They are automatically fired by the kernel.
