Not only that, they also use arrays, which are not part of standard sh.

For a POSIX-sh compliant solution thad does mostly the same thing (and handles 
multiple DOMAIN options as well, which client.{up,down} doesn't support), I 
suggest  you look into the Gentoo-provided {up,down}.sh scripts (though they 
contain some Gentoo-specific parts, but those are easily removed).
