I stand corrected on this point.

Read the CVS logs and tell me how you could interpret the comments any
differently:
1.21 Fri Jan 30 11:33:40 1998 UTC by phk
CVS Tags: HEAD
Diffs to 1.20
FILE REMOVED
Retire LFS.
If you want to play with it, you can find the final version of the
code in the repository the tag LFS_RETIREMENT.
If somebody makes LFS work again, adding it back is certainly
desireable, but as it is now nobody seems to care much about it,
and it has suffered considerable bitrot since its somewhat haphazard
integration.
R.I.P
Obviously you don't know what you're talking about either. Do you?
