Specifying multiple executable arguments using startupitems

Could be a bug. Widespread practice is to code around it and edit the launchd .plist’s in the post-activate block. You can use tcl’s reinplace or sh’s plutil as necessary to edit the .plists.

Example Portfiles that do this extensively:

• https://github.com/macports/macports-ports/blob/master/net/calendar-contacts-server/Portfile
• https://github.com/macports/macports-ports/blob/master/sysutils/clamav-server/Portfile
• https://github.com/macports/macports-ports/blob/master/mail/mail-server/Portfile
