Description Ivan Gyurdiev 2004-06-03 03:42:58 EDT

Description of problem:
Grubby has never worked for me, so I started wondering why. It always
says: Unable to find a suitable template.

That's because it's trying to --copy-default, and fails here:

if (access(fullName, R_OK)) return 0;
in function suitableImage in grubby.c
...which happens because fullName looks like this:


which I assume access does not like.

And here's the config entry I have for the default kernel:

title Fedora Linux (2.6.6 Vanilla 403)
     root (hd0,6)
     kernel (hd0,0)/vmlinuz-2.6.6-1.403 ro selinux=0 enforcing=0
root=/dev/hda7 rootflags=quota
     initrd (hd0,0)/initrd-2.6.6-1.403.img

It seems that grubby should resolve the device reference, mount it if
not mounted, and not append /boot prefix everywhere..

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Put device reference in default kernel path line
2. Run grubby

This is still broken and has been about 50 days since filed. Why?
It doesn't seem hard to fix...

Comment 2 Jeremy Katz 2004-07-26 23:34:27 EDT
Accepting patches :)

This isn't the default way we configure things and my todo list is on
the long side.  I'll hopefully get to it before FC3 is released, but
it's not something I can really promise.
Comment 3 Jeremy Katz 2004-08-04 15:44:48 EDT
Should be fixed in mkinitrd-4.0.2
Comment 4 Walter Moar 2004-08-09 16:53:36 EDT
Great to hear that this has been resolved. Will there be a new RPM (or
a patch) for those of us on RHEL using mkinitrd-3.5.13-1?
Comment 5 Ivan Gyurdiev 2004-08-09 17:24:25 EDT
Still doesn't work AFAICS. 
RPM is mkinitrd-4.0.2-1

[root@cobra tmp]# /sbin/grubby --default-kernel
[root@cobra tmp]# 

(btw this should print out a warning rather than just exit)

with this entry:

title Fedora Core (2.6.7-1.503)
     root (hd0,6)
     kernel (hd0,0)/vmlinuz-2.6.7-1.503 ro root=/dev/hda7
rootflags=quota selinux=1 enforcing=0
     initrd (hd0,0)/initrd-2.6.7-1.503.img

while it works fine with this entry:

[root@cobra tmp]# /sbin/grubby --default-kernel
[root@cobra tmp]#

title Fedora Core (2.6.7-1.503)
     root (hd0,0)
     kernel /vmlinuz-2.6.7-1.503 ro root=/dev/hda7 rootflags=quota
selinux=1 enforcing=0
     initrd /initrd-2.6.7-1.503.img
Comment 6 Ivan Gyurdiev 2004-08-09 17:32:32 EDT
By the way I realize now that the root directive is for internal grub
use and not for setting the root fs, so I can use that to make it
work, but that doesn't mean it's right the way it is... but I can see
why it's low priority for you.

I tried looking at the code some time ago but the bootPrefix stuff
didn't make sense to me - it just gets ignored by most of the functions. 

Comment 7 Jeremy Katz 2004-08-10 14:27:30 EDT
Added handling for --default-kernel bit.
Comment 8 Ivan Gyurdiev 2004-08-12 14:02:34 EDT
That's good, but it still doesn't work.
You can't --remove-kernel by path when prefixed with the device label.
You can only remove it by "TITLE=". Since you can remove kernels by
path when not prefixed, this is a bug.

Comment 9 Ivan Gyurdiev 2004-08-17 10:20:17 EDT
Ok I'm happy (for now).
