You can also just do

    portage = {
    	    inode_ratio=4096
    }

... and then "mke2fs -t ext4 -T portage" or "/sbin/mkfs.ext4 -T
portage" will do the right thing.  Note BTW, that this issue with the
inode_ratio is also true for ext3, so what I've suggested means that
"mke2fs -t ext3 -T portage" or "mke2fs -t ext2 -T portage" will also
do the right thing for an ext3 or ext2 filesystem, respectively.
