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.
