Runs fine, but appearance in ps is odd:

The actual command was:

multirun "php-fpm -F" "httpd -D FOREGROUND" "tail --retry -f /var/log/php-fpm/www-error.log"

Very minor but just wanted to note.

Seems like ps flattens the command when printing it. It's worth to know but not really related to multirun.

It could potentially be nice to override the program name to avoid having a long chain in ps but I don't think there is a portable solution to do so.
