rubepisc: My fault. I didn't check first other binaries in the initramfs...

The initramfs' /bin/dd came from the package 'klibc-utils' through the mkinitramfs (line 168):
ln -s /usr/lib/klibc/bin/* ${DESTDIR}/bin

It's a statically linked binary:
juanje@mac:~$ file /usr/lib/klibc/bin/dd
/usr/lib/klibc/bin/dd: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), statically linked (uses shared libs), stripped

So, as you said the problem is not in the busybox, but in the PATH.

That PATH is exported in the 'casper' script (/usr/share/initramfs-tools/scripts/casper) at line 5:
export PATH=/root/usr/bin:/root/usr/sbin:/root/bin:/root/sbin:/usr/bin:/usr/sbin:/bin:/sbin

I guess there is a reason for that, but I don't know if it's a problem to reverse this path list...
It could fix the problem, don't you think?

I'll try tomorrow and I'll report it here. If this is not possible, I guess the solution could be to put the absolute PATH of the static dd (/bin/dd) instead of just the command (dd).

We'll see.
