# $NetBSD: README,v 1.4 2002/03/25 07:39:50 lukem Exp $ From: "Gordon W. Ross" Date: Tue, 3 Oct 95 16:37:39 EDT Subject: New ramdisk, tiny shell, etc. [ edited since the original mail ] As part of my efforts to build a RAM-disk root kernel for the sun3 port, I've developed some things that others may want: New RAM-disk: [ see sys/dev/ramdisk.c ] New "small/tiny" tools, to replace some of the larger programs that one usually wants on a ramdisk root: ssh: (small shell) * Consumes only about 8K of memory on an m68k! (saves about 100K in the ramdisk...) * Can run programs, possibly with I/O redirection * Just enough to let you run the programs needed while partitioning and copying miniroot to swap. tls: (tiny ls) * Consumes only about 4K of memory on an m68k! (saves about 10K in the ramdisk...) * Long format only, nothing fancy. Also, in the new "src/distrib/utils" area, I've made build directories for some programs that build smaller versions, usually by adding special CFLAGS init_s: (built with -DLETS_GET_SMALL) * Forces single-user mode * Eliminates unnecessary code libhack: small implementation of some libc functions * Needs only /etc/master.passwd (not pwd.db, spwd.db) * Reduces size of an m68k crunched binary by about 64K x_dd: built with -DNO_CONV (no conv=* options) x_ifconfig: supports inet only The x_ prefix on the above is to make the names unique so crunchgen will not confuse them with the real sources.
