Grubby on F9 in livecd environ truncates kernel/initrd paths
Last modified: 2009-05-05 15:11:41 EDT
Description of problem: I'm using the koan liveCD (from fresh checkout of koan's git, with options: koan --server=mdehaan --livecd --replace-self which calls grubby as follows: /sbin/grubby --add-kernel /boot/vmlinuz --initrd /boot/initrd.img --args "ksdevice=eth0 lang= text ks=http://mdehaan/cblr/svc/op/ks/system/loaner syslog=mdehaan:25150 kssendmac " --copy-default --make-default --title=kick1217541082 --bad-image-okay ---boot-filesystem=/dev/sda1 --config-file=/tmp/boot/boot/grub/grub.conf The purpose of this is to use the Live CD to simulate PXE in environs that cannot support it, by looking up the mac and manipulating grub. This worked pretty well in F8 but now I am getting truncation in the grub.conf # grub.conf default=0 timeout=5 #splashimage=blah hiddenmenu title kick121blah root (hd0,0) kernel inuz ksdevice=eth0 lang= text ... blah initrd trd.img ... blah So you will notice that the two filenames above that should be /boot/vmlinuz and /boot/initrd.img are truncated. This prevents the OS from installing on the next boot as it can't find the files in question. When run simply with just "--add-kernel" under a normal OS, I do not have a problem. As shown in koan's checkout (koan/live) I am using the following repos to build the live CD image: repo --name=todos --baseurl=http://download.fedora.redhat.com/pub/fedora/linux/releases/9/Everything/i386/os/ repo --name=updatez --baseurl=http://download.fedora.redhat.com/pub/fedora/linux/updates/9/i386/ repo --name=newkoan --baseurl=file:///tmp/newkoan/ Version-Release number of selected component (if applicable): grubby 6.0.52 (from -v under livecd environment) The following command run from the liveCD environment, does work: grubby --add-kernel /boot/vmlinuz --initrd /boot/initrd.img --title dumb --config-file=/tmp/boot/boot/grub/grub.conf Upon further testing of various combinations, I narrowed down --bad-image-okay as the option that is causing the truncation. When using grubby to install into an unconventional location you seem to need this option. So, this defect is about finding out what is going on when --bad-image-okay is truncating the paths.
I'll simplify this. This can be reproduced on a normal F9 system. [root@localhost cobbler]# /sbin/grubby --add-kernel /boot/vmlinuz --initrd /boot/initrd.img --args "ksdevice=eth0 lang= text ks=http://mdehaan/cblr/svc/op/ks/system/loaner syslog=mdehaan:25150 kssendmac " --copy-default --make-default --title=kick1217541082 --bad-image-okay --boot-filesystem=/dev/sda1 --config-file=/boot/grub/grub.conf This will write truncated file paths just like the above into the normal grub file. Should be very easy to repro that way.
Any update on this one?
grubby is part of mkinitrd, but will take a look at this. I can reproduce it
Aha! Figured it out the problem is you should be passing --boot-filesystem=/boot (or /) depending on whether /boot is a separate filesystem or not. Not the device name
