* 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.
