From df0501a29993c4a8edc3bf9e1629ea15e1c185a0 Mon Sep 17 00:00:00 2001 From: Benedict Reuschling Date: Sat, 23 Apr 2016 20:45:52 +0000 Subject: [PATCH] The default value of MINFREE is defined to be 8% in ufs/ffs/fs.h and not 10%. The newfs(8) and tunefs(8) man pages had this change already, but fs(5) did not. This change makes it consistent again. Bump Dd.
