Description:

Cowdancer provides limited copy-on-write file access on hard-link copied
directory trees ('cp -al'). The cowdancer session is started with 'cow-shell'
command. Within that session, cowdancer will create a new file when existing
inode is opened for a write operation. The list of protected inodes is
generated on session start from directory tree where 'cow-shell' was invoked.
Tool is completely implemented in userspace and uses LD_PRELOAD technique.

Limitations:
- support for chmod/chown is not reliable
- requires filesystem supporting hard-links
- operation is not semantically correct when files are originally hard-linked
- if chroot is needed, has to be started from inside of it
- is silent and does nothing when LD_PRELOAD breaks
