Raspberry Pi install image from 
ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-7.0/evbarm-arm/binary/gzimg/rpi_inst.img.gz
System not yet installed.
>Description:
When trying to install NetBSD to a Raspberry Pi from FTP-Server, the default path in sysinst points to /pub/NetBSD/NetBSD-7.0/evbarm/ while the correct path would be /pub/NetBSD/NetBSD-7.0/evbarm-arm/ . 

>How-To-Repeat:
Install NetBSD 7.0 on a Raspberry Pi by booting rpi_inst.img from SD-Card, sysinst gives the wrong FTP server path by default. 
>Fix:
Change default path from /pub/NetBSD/NetBSD-7.0/evbarm/ to /pub/NetBSD/NetBSD-7.0/evbarm-arm/

 Just a side note (the issue reported here is real and should be fixed!):

 Since you are installing from scratch, 
 you should prefer to install evbarm-earmv6hf on RPi.

 (yes, it IS confusing)

 The underlying issue is a lot of confusion which ABI is used by default
 on what ARM port.

 Since evbarm defaults to oabi (i.e. evbarm == evbarm-arm) the path used
 by sysinst here *could* be considered correct and as a fix the ftp setup
 be changed (by adding a symlink).

 However, the same problem then shows up with evbarm-earm.

 So sysinst encodes this information here:

 main.c: {"ftp prefix", "/" MACH "/binary/sets", set_dir_bin, sizeof set_dir_bin},

 and MACH comes from Makefile.inc:

 	-DMACH=\"${MACHINE}\"

 I suggest to create a new -DFTP_MACH and use it for both the ftp prefix as
 well as the pkg path default (currently also using MACH).

 Then default FTP_MACH to MACH if not overriden by the arch, and override it
 on arm depending on the ABI in use.
