CentOS - Sep 2006 - Trimming the fat out of a Centos 4.4 Installation

Hi, just to avoid re-inventing the wheel, is there any document that
can help me reduce even further a "minimum" installation of Centos 4.4
(BTW can you say 600mb is minimum)?

I am in the process of creating a small Centos-4.4-based Asterisk box
and I need to boot it from a CF card. Deleting useless packages will
help me do what i want.
Example: even a minimum install of Centos 4.4 (or Redhat EL for what
is worth) includes CUPS, among other things.

Any document hyperlink will be more than welcomed!!

The result will be posted to the link for others to use.

Yes, isn't it insane?

I usually just start with:

rpm -qa --queryformat "%{SIZE}\t%{NAME}\n" | sort -nr | less

and then start in with:

rpm -e packagename

noting what dependencies each package wants to take with it, of course.

Then, when I reach a point of diminishing returns with that, I switch
strategies:

cd /
du -ak | sort -nr | less

And start hacking away at any obvious offenders.  This breaks package
integrity, of course, but on CF, you may not care.

And then, just on general principles,  because I simply detest the
wretched, bloaty thing, and all its associated detritus:

find / -name "*emacs*" | sort -nr | less

And then I call RMS at 2AM to tell him how much I despise it... but I
fear I'm veering off topic. ;-)

it is yes, the base minimum is what App and Solution vendors are then 
able to assume will be the minimum functional level of a machine, 
running CentOS.

it comes from the LSB compatibility specifications. cups is required as 
is a MTA and a bunch of other things.

if you really want to trim down, get yum going and rpm -qa, check what 
you dont want, then remove it.

You did google for this correct? Tiny Centos reveals first hit success.

Assuming they look for it :-P

This is my 'minimal base' that I start from.  You could remove the lvm2
stuff as well.  It will do an install of 163 packages and take about
540M of disk.  About the only thing you will have is ssh and yum.  For 
a card, you obviously want to change the disk layout.

Apply all the other comments to this one.
