rsync to clone disk - Can it work? grub-install error

[chloe K <chloekcy2000@yahoo.ca>]

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?

Thank you
