      3  1.1    gwr From: "Gordon W. Ross" <gwr>
      4  1.1    gwr Date: Tue, 3 Oct 95 16:37:39 EDT
      5  1.1    gwr Subject: New ramdisk, tiny shell, etc.
      6  1.1    gwr [ edited since the original mail ]
      7  1.1    gwr 
      8  1.1    gwr As part of my efforts to build a RAM-disk root kernel for the
      9  1.1    gwr sun3 port, I've developed some things that others may want:
     10  1.1    gwr 
     11  1.1    gwr New RAM-disk: [ see sys/dev/ramdisk.c ]
     12  1.1    gwr 
     13  1.1    gwr New "small/tiny" tools, to replace some of the larger
     14  1.1    gwr programs that one usually wants on a ramdisk root:
     15  1.1    gwr 
     16  1.1    gwr ssh: (small shell)
     17  1.1    gwr   * Consumes only about 8K of memory on an m68k!
     18  1.1    gwr     (saves about 100K in the ramdisk...)
     19  1.1    gwr   * Can run programs, possibly with I/O redirection
     20  1.1    gwr   * Just enough to let you run the programs needed
     21  1.1    gwr     while partitioning and copying miniroot to swap.
     22  1.1    gwr 
     23  1.1    gwr tls: (tiny ls)
     24  1.1    gwr   * Consumes only about 4K of memory on an m68k!
     25  1.1    gwr     (saves about 10K in the ramdisk...)
     26  1.1    gwr   * Long format only, nothing fancy.
     27  1.1    gwr 
     28  1.1    gwr Also, in the new "src/distrib/utils" area, I've made build
     29  1.1    gwr directories for some programs that build smaller versions,
     30  1.1    gwr usually by adding special CFLAGS
     31  1.1    gwr 
     32  1.1    gwr init_s:  (built with -DLETS_GET_SMALL)
     33  1.1    gwr   * Forces single-user mode
     34  1.1    gwr   * Eliminates unnecessary code
     35  1.1    gwr 
     36  1.1    gwr libhack:   small implementation of some libc functions
     37  1.4  lukem   * Needs only /etc/master.passwd (not pwd.db, spwd.db)
     38  1.2    gwr   * Reduces size of an m68k crunched binary by about 64K
     39  1.1    gwr 
     40  1.1    gwr x_dd:  built with -DNO_CONV (no conv=* options)
     41  1.1    gwr 
     42  1.1    gwr x_ifconfig:  supports inet only
     43  1.1    gwr 
     44  1.1    gwr The x_ prefix on the above is to make the names unique so
     45  1.1    gwr crunchgen will not confuse them with the real sources.
