>Description:

Doing a reproducable build of netbsd-8 on a -current build host
results in a few differences in the release.

All .ps.gz files differ, mainly by page size.

This might come from my environment (or something), but I don't
see how it happens exactly.

A sample diff is below.

 Maybe a clue: 612 792 = 8.5 x 11 inch = letter
               595 842 = 210 x 297 mm  = A4

 Yes, but why is it different on my local system? I thought I would have
 to pass something like -P-pa4 to groff to ask for A4, but I don't see
 where that would be coming from.

 Perhaps:
 # cat /usr/pkg/etc/papersize
 a4

 Heh, I have that on most systems, but actually not on the build host
 in question.
