Initial preparation

  1. Download and set up a VEOS instance with the matching EOS version
  2. Create a 3GB disk and attack to the VEOS instance (used as a scratch disk)
  3. Boot the VEOS guest

After boot

Partition the second disk to use for additional space,

sudo -i
mkfs.ext2 /dev/sdb1

Mount the new partition and bind mount directories,

mkdir -p /mnt/sdb1
mount /dev/sdb /mnt/sdb1
mkdir -p /mnt/sdb1/{bin,var/cache/yum,usr}
rsync -axpHSD --numeric-ids -vP --delete /var/cache/yum/ /mnt/sdb1/var/cache/yum/
rsync -axpHSD --numeric-ids -vP --delete /usr/ /mnt/sdb1/usr/
rsync -axpHSD --numeric-ids -vP --delete /bin/ /mnt/sdb1/bin/

mount --bind /mnt/sdb1/var/cache/yum /var/cache/yum
mount --bind /mnt/sdb1/usr /usr
mount --bind /mnt/sdb1/bin /bin

Add the Fedora repos

cd /etc/yum.repos.d/

cat > fedora.repo <<EOF
