Besides:

siovene at sd024:/work/trunk/libraries$ sh -c "echo \$HOSTNAME"
sd024
siovene at sd024:/work/trunk/libraries$ /bin/sh -c "echo \$HOSTNAME"
sd024
siovene at sd024:/work/trunk/libraries$ ls -lh /bin/sh
lrwxrwxrwx 1 root root 4 2007-11-13 16:18 /bin/sh -> bash

So sh is actually bash, on my machine.
