Method one:  
-----------------------------

Find a spare/unused disk partition with lots of space.  Use 'dd'
to stuff root_fs-i386 onto the spare partition. i.e.

    dd if=root_fs-i386 of=/dev/hdX1

then run 

    fsck.ext2 -f /dev/hdX1

then use resize2fs to resize it to fill the partition.

    resize2fs -P /dev/hdX1

then you have a full partition with as much space as you need,
and you can even setup grub or whatever to boot into your
partition, or you can chroot into it, or pivot_root into it,
or whatever.


Method two:
-----------------------------

Loop mount root_fs-i386 somewhere, i.e. 

    mount root_fs-i386 /mnt -o loop

then bind-mount somewhere on your root filesystem inside the
root_fs-i386 loop mount.  i.e.

    mount /home/cholbrook/uClibc.stuff /mnt/home -o bind

and now if you chroot into /mnt, you will find the /home
directory is actually /home/cholbrook/uClibc.stuff on your
system's root filesystem, which as much free space as your
root filesystem has to offer.
