Rather than trying the following, I thought, "Why not ask first?"
Due to the sizes of various hard disks in my machine, I want to move /gnu
and then do
mount --bind /directoryondifferentdisk/gnu /gnu
(I have already formed a superstition that
ln -s /directoryondifferentdisk/gnu /gnu
I see a vast collection of hard links in /gnu/store/.links...
I forsee problems when copying /gnu, not reproducing hard links
but reproducing the data.
Are my fears founded? How to proceed?
Or better to start over with new installation of gnux and /gnu?
