groff issue after upgrade to NetBSD-9.2

[steve%prd.co.uk@localhost (Steve Blinkhorn)]

This is on amd64, but I doubt that that's relevant.

I have an extensive collection of fonts for PostScript, so
/usr/share/groff_font/devps is a symbolic link to a /fonts directory.  It
has been so since NetBSD-1.x and before that on BSD/OS and before that
into the mists of time.

I upgraded to NetBSD-9.2 several days ago, and suddenly my standard
document formats come out all wrong.  The glyphs for the
variously-acquired (e.g. bought from Linotype) fonts do not seem to be
available, and the font metrics are wrong for the glyphs that do
appear.

I have a practical solution for the moment: if I mount_nfs a backup
copy of the same fonts directory on a remote server and point
groff_font/devps at that instead, everything goes back to normal.

Anyone have any insight into why migrating from 7.0 to 9.2 might cause
such a problem?
