For reference, this, using the perl utility from syslinux:

$ sha1pass pass salt
$4$salt$bZuH+MGRe/PzSo19kyjHeYHQT+k$

ought, so far as I have understood the relevant documentation, and the
code for perl-digest-sha1, be reproducible as follows:

$ printf '$4$%s$%s$\n' salt $(echo saltpass | openssl dgst -sha1 -binary | base64 | sed 's/=$//')
$4$salt$PKE3LoCWMo+QH2d2luTjhakNfFs$

However, as you can see the results are not the same. So there's
some piece here that I haven't yet understood.
