I face to some problem, I use livecd-iso-to-pxeboot to build a tftpboot/.
DEFAULT pxeboot
TIMEOUT 20
PROMPT 0
LABEL pxeboot
KERNEL livecd/vmlinuz0
APPEND rootflags=loop initrd=livecd/initrd0.img root=live:/CentOS-6.3-x86_64-LiveCD.iso rootfstype=auto ro liveimg nodiskmount nolvmmount rhgb vga=791 rd.luks=0 rd.md=0 rd.dm=0 rd.live.check
ONERROR LOCALBOOT 0
But someting wrong in root section
cannot open root device "live:/CentOS-6.3-x86_64-LiveCD.iso"
I want to find out where CentOS-6.3-x86_64-LiveCD.iso It put into initrd0.img
I extract the content of initrd0.img, but when I extract coip img, 700mb content become 21m
I can't find where the CentOS-6.3-x86_64-LiveCD.iso is.
Then I found the code of livecd-iso-to-pxeboot
( cd "$ISODIRNAME" && echo "$ISOBASENAME" | cpio -H newc -L -o ) |
gzip -9 |
cat $CDMNT/isolinux/initrd0.img - > tftpboot/initrd0.img
I can't understand why this commend is using cat to put two file, initrd and iso together.
