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