+.SH DEPRECATED OPTIONS

+.B net <nfs mount>|<user@server>
+.RS
+net option is replaced by nfs and ssh options. Use nfs or ssh options
+directly.
+.RE
+
+.B options <module> <option list>
+.RS
+Use KDUMP_COMMANDLINE_APPEND in /etc/sysconfig/kdump to add proper
+module option as kernel command line params. Such as append loop.max_loop=1
+to limit maximum loop devices to 1.
+.RE

+.B link_delay <seconds>
+.RS
+link_delay was used to wait a network device to initialize before using it.
+Now dracut network module take care of this issue automaticlly.
+.RE
+
+.B disk_timeout <seconds>
+.RS
+Similar to link_delay, dracut ensures disks being ready before kdump uses them.
+.RE
+
+.B debug_mem_level <0-3>
+.RS
+This was used to turns on debug/verbose output of kdump scripts regarding
+free/used memory at various points of execution.  This feature has been
+moved to dracut now.
+Use KDUMP_COMMANDLINE_APPEND in /etc/sysconfig/kdump and
+append dracut cmdline param rd.memdebug=[0-3] to enable the debug output.
+
+Higher level means more debugging output.
