No sudo, no root, on a fully encrypted LVM filesystem

[David Starner <prosfilaes@gmail.com>]

I've managed to remove suid bits from all the files in my /usr/bin
directory. As I have no root password, and I have a fully encrypted
LVM filesystem, I'm at loss at how to recover them without deleting
everything and starting all over. (It's not a disastrous option, I
guess, since it's a fairly fresh install, but I'd rather not.) If I
backed up the / partition, reformatted and restored it to an
unencrypted partition that I could edit from a bootable disk, would
that work, or would LVM get in my way?
