+### Please describe the problem.
+
+There exist more BSD systems than FreeBSD. Thus I propose diff for Utility/libdiskfree.c.
+
+Based on pkgsrc patching guidelines https://www.netbsd.org/docs/pkgsrc/components.html#components.patches.guidelines
+I tried to cook a diff even I'm not C developer.
+
+
+### What steps will reproduce the problem?
+
+Add support for more OS for disk free check.
+
+### What version of git-annex are you using? On what operating system?
+git-annex-5.20150930
+
+
+### Please provide any additional information below.
+
+The diff probably needs check, improvement...

+### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
+
+Not tested this "feature" yet, I got another issue which blocks me for now.
