DF2 has proven popular.  Here is a child of it which supports
System V Release 3 or 4.  I am also submitting a patch to the
first df2 from Chip Salzenburg for the original to do NFS
support.

My goal was to customize a df for my needs and to make the code
available for others to do likewise.  Note my original had just
enough room for my longest mount directory :-).  80 characters is
not a lot of room for the wide range of stuff you want to print.
We all are likely to customize.

So, with this version and Chip's NFS patches to the original, we
have a better collection of code and fragments to each build our
idea of a "df -me" dream hack.

XPaul Slootman has ported it to System 5 Release 4 (does he REALLY
Xhave all that disk ?? :->).
X
Xit is still easy to make, though the needed library and the compile
Xoptions have prompted a Makefile.  Read and edit the Makefile as
Xnecessary and just make it.

XHi,
X
XI snarfed your df2 from the net, and have ported it to System V.4
X(on an ICL DRS6000 Sparc). It needed a few adjustments to allow
Xfor the virtual filesystems, but seems to be running ok for now.
XI'm going to extend it to take into account that some filesystems
Xhave a requirement that some percentage of the disk MUST be free
X(i.e. a normal user may only use up to 90%; beyond that he gets a
X"filesystem full" error). This is something the standard df doesn't
Xhandle. (When it's 89% full, that's what it says. When it's 90%
Xfull, df states 100% full -- which can be confusing "Hey just a
Xmoment ago it said 89%!!!").
XThe percentage is rounded now. That's the usual way.
XA small cosmetic adjustment has also been made - the filesystem
Xnames are longer. Eg.:
X                                   Size (kb)                  Inodes
