Hello,

It is curious for me that ".jpg" has two entries in /sys/lib/mimetype.
term% grep jpeg /sys/lib/mimetype
.jfif		image		jpeg		-		y
.jfif-tbnl	image		jpeg		-		y
.jpe		image		jpeg		-		y
.jpeg		image		jpeg		-		y
.jpg		image		jpeg		-		y
.jpg		image		pjpeg		-		y
term%

The file is currently consulted by only two applications: mail and =
httpd.
I thought that the file provides conventional way to determine mime type =
from file suffix.
If so, what is the mime type for "foo.jpg"?
