fl-cow: fl-cow (copy-on-write utility)
fl-cow:
fl-cow: Fl-cow is an LD_PRELOAD library which allows you to utilize hardlinks
fl-cow: to save disk space by causing hardlinked files to be copied rather
fl-cow: than overwritten as they are changed.
fl-cow: This is useful for making changes to large source trees while keeping
fl-cow: a copy of the original tree to generate patches from. Also, if you are
fl-cow: using the Arch revision control system with working copies hardlinked
fl-cow: to a revision library, using fl-cow can prevent revision library
fl-cow: corruption.
