[Yum] local "base"?

[Morgan Read]

Hi Karsten,
Thanks very much for the follow up.  I realise there seem to be a couple 
of threads going on more or less the same topic, but from your msg's, if 
I simply do in yum.conf:

------------
[local]
name=Local Packages
baseurl=file:///usr/local/rpms+binpkgs=yumrepo
...
[base]
name=Fedora Core $releasever - $basearch - Base
baseurl=ftp://ftp.wicks.co.nz/pub/linux/dist/fedora/$releasever/$basearch/os
-----------
Instead of:

-----------
[base]
name=Fedora Core $releasever - $basearch - Base
baseurl=ftp://ftp.wicks.co.nz/pub/linux/dist/fedora/$releasever/$basearch/os
...
[local]
name=Local Packages
baseurl=file:///usr/local/rpms+binpkgs=yumrepo
-----------

And when I make changes (eg mount or unmount an fc3 dvd at 
/usr/local/rpms+binpkgs=yumrepo/mount) run:
#createrepo -q -p /usr/local/rpms+binpkgs=yumrepo

I should be fine?

Regards,
Morgan.
