the Embedix release.

0.41
- * New App: wc -- contributed by Edward Betts <edward@debian.org>
+ * New Apps: wc, hostid, logname, tty, whoami, yes -- all contributed
+ by Edward Betts <edward@debian.org>
* Fixed a bug in both cp and mv preventing 'cp foo/README bar'
type commands (file in a directory to another directory)
from working.
* Added -o loop option for mount, and support in umount for loop
devices. Support is toggled by MOUNT_LOOP feature -- Ben Collins
<bcollins@debian.org>
+ * Several fixes from Marco Pantaleoni <panta@prosa.it>
+ * compile in fullWrite() not only if BB_TAR is defined, but also
+ if BB_CP or BB_MV are (fullWrite() is referenced by copyFile())
+ * add some compiler optimizations to further reduce executable size
+ (as a side note, on my machines the largest code is generated by
+ gcc 2.95.2 with -Os ! The smallest by plain gcc 2.7.2.3 with -O2
+ -m386 ...)
+ * Compile no longer fails if busybox.def.h defines BB_FEATURE_LINUXRC
+ but not BB_INIT. (init_main used to be referenced, but not compiled)
+ * Fixed a bug in setting TERM for serial console support. TERM now
+ defaults to "ansi" for serial consoles.
+ * Fixed a bug in handling the CONSOLE env. variable for serial consoles.

# -D_GNU_SOURCE is needed because environ is used in init.c
* login/sulogin/passwd/getty/etc are part of tinylogin, and so are not
needed or wanted in busybox (or else I'd have to link in libcrypt).
+* Networking apps are probably going to be split out some time soon into a
+ separate package (named perhaps tiny-netkit?). This currently includes
+ hostid, hostname, mnc, and ping.
