>Description:
When no swap space is configured during install, sysinst doesn't automatically set "no_swap=YES" in /etc/rc.conf, which results in swap2 complaining and creating errors each boot. swap2 also doesn't mention this error can be ignored by setting no_swap=YES in /etc/rc.conf
>How-To-Repeat:
Install NetBSD without any swap space configured
>Fix:
Either
- make swap2 suggest adding no_swap=YES to /etc/rc.conf if not configuring swap space was a deliberate action
- make sysinst automatically set no_swap=YES in rc.conf when no swap space is configured

 This makes sense, especially when sysinst avoids creating swap space
 like on evbarm with root on SD media via MD_MAY_SWAP_TO defined
 as may_swap_if_not_sdmmc.
