+CHANGES IN THE LINUX v0.97 ROOT DISKETTE
+Jim Winstead Jr. - 4 August 1992
+
+This file mostly contains info about the changes in the root diskette
+from Linux v0.96 to Linux v0.97.
+
+BUGS
+
+	'mount' is broken in strange ways, particularly in passing
+	options '-o whatever'.  I'm working on this.
+
+CHANGES
+
+With the release of Linux v0.95a, the maintenance of the root diskette
+has been assumed by Jim Winstead Jr. (jwinstea@jarthur.Claremont.EDU).
+
+This continues with the release of the Linux 0.97 release diskette.
+The changes between the Linux 0.97 and Linux 0.96 root diskettes are
+detailed below, and the changes in earlier releases are summarized
+after that:
+
+	-	many small binaries were added, including: 
+
+			cmp cut date env find head id install logname nice
+			nohup pathchk printenv printf sed setserial sort sum
+			tac tee tr tty uname uniq wall wc who whoami write yes
+
+		(Some of these may have been on previous root disks -
+		I don't have the motivation to double check that.  In any
+		case, they are definitely on 0.97.  :)
+
+	-	ps, w, uptime, and related utilities were removed.
+		Because these programs rely very closely upon the
+		kernel being used, they can be outdated quite quickly.
+
+	-	migrated mount/umount/swapon from /bin to /etc.
+		This conforms to common usage (only root can use these
+		programs), and current standards.
+
+	-	moved 'rootdev' to /usr/bin and renamed to 'setroot'.
+		This reflects more common usage of the utility - it is no
+		longer needed for inserting the root device in /etc/mtab, but
+		it is still useful to change the root device of a kernel image.
+
+	-	removed /lib/libhard.2.2.2 and moved /lib/libsoft.2.2.2 to
+		/lib/libm.2.2.2, instead of using a symlink.
+
+	-	upgraded efdisk and renamed to fdisk.
+		efdisk was upgraded to v0.93, from Owen LeBlanc's MCC 0.96c
+		interim release, with some small changes from me to support the
+		-l flag, allowing it to completely replace fdisk.
+
+	-	fixed compress to work with long filenames.
+		Previous versions of compress would refuse to compress files
+		with names longer than 12 characters - this was hardcoded in
+		the source the FSF makes available.
+
+	-	brought device names up to standards.
+		Fixed some device names according to decisions made on
+		the Linux Standards discussion list, particularly
+		renaming /dev/lp* to /dev/par*, 'hard' /dev/fd*
+		devices, /dev/bm (bus mouse), and fixing the numbering
+		of /dev/ttys*.
+
+	-	revised /etc/group.
+		/etc/group now contains only the 'standard' group names
+		discussed in the Linux Standards list.  Of special note is the
+		renaming of the 'bin' group to 'obsolete'.
+
+		Using the 'bin' group as a means of identifying executables is
+		not recommended.  That is what the executable bits are designed
+		to do.
+
+	-	revised /etc/passed.
+		/etc/passwd was changed as a result of the new /etc/group, and
+		to eliminate unnecessary usernames - many groups were removed
+		because using uid != 0 for important files is a security hole
+		on NFS-mountable drives
+
+	-	changes file permissions and ownerships.
+		This was done to reflect changes in /etc/group and /etc/passwd.
+
+	- 	fixed up the install script where it was broken.
+		All known major bugs were fixed.  Particularly where /usr was
+		concerned.
+
+	-	fixed the install documentation to refer to pax.
+
+	-	minor gaffes from 0.96 fixed (/etc/getty linked with
+		shared libs, correct file ownerships, etc)
+
+If you have questions, problems, or complaints about the root
+diskette, either post to comp.os.linux, or send mail to me at
+jwinstea@jarthur.Claremont.EDU. 
+
+If you have questions, problems, or complaints about the boot diskette
+or the kernel itself, post to comp.os.linux or send mail to Linus
+Torvalds at torvalds@cc.helsinki.fi.
+
+Remember, the only stupid questions are the ones you don't ask.
+
+SUMMARY
+
+This section very briefly summarizes previous changes.
+
+0.95a -> 0.96
+	- reintroduced GNU bash as /bin/sh
+	- replaced GNU tar (/bin/tar) with POSIX pax utility
+	- all-new and improved installation script
+	- split /etc/rc into /etc/rc and /etc/rc.local
+	- new mount/umount/swapon with auto-mounting - uses /etc/fstab
+	- recompiled all utilities with shared libraries (gcc 2.2.2)
+	- added /dev/MAKEDEV - device creation script
+	- all new /etc/termcap using "tc=con-unk" entries
+
+FUTURE CHANGES
+
+I'm already anticipating some changes for future releases, so here's
+a sneak preview:
+
+-	the install script will be improved.  The current one was
+	written rather rapidly, so there are parts of it I'm not
+	entirely happy with.
+
+-	I'd like to write an update script that will allow people who
+	have already installed Linux to update their binaries from the
+	latest root disk.  The install script could serve as a base
+	for this, but is a little destructive at present.  (It would
+	simply copy over old binaries, etc.)
+
+-	program to allow the 'intro' login to be more interactive, and
+	will also serve more general purposes (it will be a generic
+	curses-based file-selector with support for file descriptions).
+
+-	the documentation on disk will be cleaned up, and possibly
+	added to.
+
+-	fill in the gaps in the MAKEDEV script.  (SCSI tapes, more pty
+	devices.)
+
+-	the release after the extended filesystem is added to the
+	Linux kernel, the root disk will use it.  That means v0.98, if
+	things go according to current plans.  This is to allow time
+	for bugs in the extended filesystem to filter out, and for the
+	new mkfs and fsck to stabilize.  (For those that don't know,
+	the extended filesystem supports 4 terabyte partitions and long
+	filenames, and is currently in testing.)
+
+Again, mail your questions, comments and suggestions about the root
+diskette to me at jwinstea@jarthur.Claremont.EDU.
