free). Use of /proc (or not) is policy that should be set up in
/etc/fstab (or in hardcoded scripts), not in init.
* Fixed rebooting when init runs as an initrd.
+ * Fixes and updates from Karl M. Hegbloom <karlheg@debian.org>
+ - update.c rewritten to look more like update-2.11
+ - moveed the inode hash out of du.c and into utility.c to make
+ it a common resource that can be used by other apps.
+ - cp_mv.c now checks inodes to see if a source and dest are
+ the same, and prints an error (instead of endlessly looping).
+ - mv now attempts to do a rename, and will fall back to doing
+ a copy only if the rename fails.
+ * Several fixes from Pavel Roskin <pavel_roskin@geocities.com>:
+ - Fixes to sort. Removed "-g", fixed and added "-r"
+ - Fixes to the makefile for handling "strip"
+ * An initial telnet implementation was added by
+ Randolph Chung <tausq@debian.org>.

syslog box, right? I can see that this would be useful.
I'll add this to the TODO list,
+
+-----------------------
+
+
+ In utility.c:copyFile: It uses followLinks for both source and
+ destination files... is that right for `mv'? Will need to revisit
+ the GNU, freeBSD, and MINIX versions for this... Should read the
+ Unix98 and POSIX specs also.
+
+-----------------------
+
+ I think that the add_inode &c in utility.c needs to also stow the
+ st_dev field, and that du.c should NOT call `reset_inode_list'
+ because there can be hard links from inside one argv/ to inside
+ another argv/. du.c probably ought to have an -x switch like GNU du
+ does also...
