Filesystem in F11 builds

This problem and my implementation are independient. If I make a build
without the dracut modulethe filesystem is the same.
My idea is remount /home partition from nand to sd card. During pre-pivot
stage is the best option to do that, because /home partition is already
mounted but root system is not switched yet.
The script is something like this:
writable_start || die
mkdir -p $NEWHOME
if [ -b $SD_CARD ]; then
mount $SD_CARD $NEWHOME
umount $NEWROOT/home || die
mount --bind "$NEWHOME/home" "$NEWROOT/home" || die
echo "user home is mounted in $SD_CARD"
writable_done || die
