* Busybox can now work perfectly when /proc is disabled, thereby
- saving a bunch of memory (kernel /proc support is not thin).
- This is done by making use of some nice kernel patches I
- wrote up to support the features that busybox requires and
- that /proc usually provides.
+ saving a bunch of memory (kernel /proc support is not thin). This
+ is done by making use of some nice kernel patches I wrote up to
+ support the features that busybox requires and that /proc usually
+ provides. To enable this, turn on BB_FEATURE_USE_DEVPS_PATCH and
+ patch your kernel with the devps patch in the kernel-patches/
+ directory.
* Wrote basename, killall, and uptime.
* Added freeramdisk, which will free up all memory associated
with a ram disk. Contributed by Emanuele Caratti <wiz@iol.it>
