Filesystem in F11 builds

[Esteban Bordon]

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"
    umount $NEWHOME
fi

writable_done || die
