grub.conf文件中有關內核參數(shù)的問題

夏織風

我借此機會先給各位大神們拜個晚年！祝大家新年萬事如意！
此為我的grub.conf文件中的信息：
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.

#          initrd /initrd-[generic-]version.img

請問各位大神如下內核參數(shù)代表的是什么意思：
rd_LVM_LV=vg_kzoubt/lv_swap
rd_NO_LUKS
rd_NO_MD
rd_LVM_LV=vg_kzoubt/lv_root
rd_NO_DM

這些內核參數(shù)和Kdump有關系嗎？
萬分感謝！
