From 31f4b526a608382b0969c11ebab85aabd2f06b35 Mon Sep 17 00:00:00 2001 From: mckusick Date: Thu, 16 May 2013 20:07:08 +0000 Subject: When running the -m option to generate a newfs(8) command suitable for recreating the filesystem, check for and output the -i, -k, and -l options if appropriate. Note the remaining deficiencies of the -m option in the dumpfs(8) manual page. Specifically that newfs(8) options -E, -R, -S, and -T options are not handled and that -p is not useful so is omitted. Also document that newfs(8) options -n and -r are neither checked for nor output but should be. The -r flag is needed if the filesystem uses gjournal(8).
