From: chloe K on 4 Dec 2007 15:40 Hi all I install etch in hda then I add the hdc which have same partition but not same size in hda /dev/hda1 /boot /dev/hda2 /swap /dev/hda3 / i use rsync to copy data from hda to hdc I use fedora5 boot disk to boot. mount /boot and / and chroot to / but I got error to grub-install /dev/hda You shouldn't call /sbin/grub-install. Please call /usr/sbin/grub-install instead! tempnam: No such file or directory /usr/sbin/grub-install: line 394: $log_file: ambigous redirect What is the problem?

On a side note I tend to use file system labels now rather than partition numbers as then if you have 2 IDE chipsets and they get picked up in a different order it doesn't matter, if you do that you must remember to relabel your partitions on hdc as I'm not sure what happens if you have 2 partitions of the same name. [0] I could use dd if=/dev/hda of=/dev/hdc bs=446 count=1 to copy the boot sector but not the partition table) -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe".

Is / all on one partition? What are the permissions on /tmp? and does /bin exist at this point? > > > Yes, I did > > > > but I got error to grub-install /dev/hda > > > > You shouldn't call /sbin/grub-install.

But they all center around the use of /tmp and /bin/tempfile. I think somehow you're getting a null $log_file and thus causing this ambiguous redirect. I'm not sh pro by any stretch, so ymmv. A |
