centos.cfg

# so far tested with netinstall iso, 64bit and centos 6.2
# also tested with minimal iso that contains a package repository

# you need a centos iso, of any kind.

# make /centos dir
# copy kernel + initrd to /centos  (files : vmlinuz, initrd.img)

# copy images/install.img to /centos/images/install.img
# you can put the install.img elsewhere, just fix the stage2= parameter path fragment to point to it

# you can replace LABEL=SOMELABEL with UUID=SOMEUUID, if you want to.

# if you are using other media than netinstall : 
# copy the entire centos iso image to /centos (yes, do not unpack it)
# and boot with the second menu option. the installer will mount that iso image and use it as a package repository
# during installation
