Look great, but IMO, your addition, "(passwd:name (getpwuid (getuid))))",
should be the only way to get the username since $USER and $LOGNAME
could be overridden or unset.

I don't always do it in my own scripts, but it is better to do not relay on
env vars when you want something to be bulletproof.

Since there is "passwd:dir pw", $HOME could be replaced with it too.

Thanks,
