From ded3fc6b56fe2612d565d7d812316276cf6beefe Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Thu, 24 Apr 2014 10:17:18 +0100 Subject: utils: Add hardlinkdir shell function In a number of places it would be helpful to be able to copy trees of files using hardlinks. This turns out to be harder than you'd expect since there is no good single command that does this well and handles all file types correctly. Abstracting this into a function therefore makes sense, cpio seems as good an option as any other.
