# cacerts is a relative symlink, which doesn't work when we repackage.  Make it
# absolute.  We could use tar's --dereference option, but there's a subtle
# difference between making the symlink absolute and using --dereference.
# Making the symlink absolute lets the consuming system set the cacerts; using
# --dereference takes the producing system's cacerts and sets them in stone.  We
# prefer the flexibility of the former.
