Some of these "ancient" papers are the papers of Rosenblum et al. which are
the reference papers, and how the FS does on their Sprite OS (if I recall
correctly).
The person who adapted it on NetBSD has the papers here:
	http://www.hhhh.org/perseant/lfs.html

The papers ROSE90, ROSE92 and SELT93 are quite important to read. If you own
the book `The Design and Implementation of the 4.4 BSD Operating System'
(ISBN 0-201-54979-4) then read section 8.3, as it should cover most
important things about LFS.

The overal effect on disk space should be negligible, however, it does solve
another problem, which is inode shortage.
