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/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.
