I am keeping my dotfiles under version control and the script deploying them creates hard links. I also use
etckeeper to put my
/etc under version control. Recently I have gotten warnings like this:
warning: hard-linked files could cause problems with bzr
A simple copy (
cp filename.ext filename.ext) will not work:
cp: `filename.ext' and `filename.ext' are the same file
Renaming/moving a file - except across volumes - also doesn't break the hard-link.
So my question is: is there a way to break a hard-link to a file without actually having to know where the other hard-link/s to that file is/are?
