of course you can emerge doing a stage 3 networkless install. i just did one
according to the install manual (i assume you read the install manual) you have to extract the portage snapshot from the Universal LiveCD. the tarball is in the /snapshots directory on the cd, then just mount the cd and extract it out using
Code:
tar -xvjf /mnt/cdrom/snapshots/portage-20040710.tar.bz2 -C /usr
make sure you use a capital C and not a lower case c. of course substitute your mount point for the cdrom
then copy over the source cde
Code:
mkdir /usr/portage/distfiles
Code:
cp /mnt/cdrom/distfiles/* /usr/portage/distfiles/
then to install the kernel sources for 2.4 kernel
Code:
emerge gentoo-sources
or for a 2.6 kernel
Code:
emerge gentoo-dev-sources
or
Code:
emerge development-sources
for a vanilla 2.6 kernel
also, if there is a line GENTOO_MIRRORS in your /etc/make.cnf file, just comment it out. that should pull off the cd.
of course i just did my first gentoo install so i am a gentoo n00b, but i got this all from the install guide
good luck
