After some waffling I put it in "posix", even though it was last specified in
susv2 (where it was the obsolete 6 byte header entries predating susv4).
LSB specifies it, including the 8 byte header fields, but for the actual
command it just references SUSv2. (LSB isn't so much a standard as Red Hat's
"notes to self".)

Stripping leading / is not the right thing to do there.
Broken when the code moved to lib and was genericized for use elsewhere.

implementation FLAG_xxx macros are generated for long options too. with __-__ sign in the macro, it will generate errors.
I am of the opinion that __-__ be converted to '_' for generating the FLAG_xxx macros and be used in the command.
This will enable the user to 'abc-def', but be handled like 'abc_def' in code.

own memory (instead of using toybuf), use perror_msg() instead of lower level verror_msg() (which is really an internal function needed to implement perror_msg()), don't set execute bits on created archive.

-iot combinations, move loopfiles_stdin() down after write_cpio_member() so we can hardwire it instead of using a function pointer that only ever has one value.

optional cleanup under if (CFG_TOYBOX_FREE) guard.

1. freeramdisk - If we unmount or detach the RAM disk based file system the Linux Kernel
will not free the allocated memory associated with the RAM device. This can be useful if
one wants to mount this device again: All data will be preserved.
If we need to free the memory back to the Kernel, one can use the command: "toybox freeramdisk <RAM device>".
2. openvt - Successfully opens a new virtual terminal as mentioned with -c option
otherwise search and open next available VT.
with -s option it switches to new VT
with -s -w option, it switch back successfully to originating VT.
3. deallocvt - Deallocate specified virtual teminal.
if no virtual terminal is specified, it deallocates all unused VT.

string.
You shouldn't use "" as an option string because a NULL allows toy_init()
to avoid calling the option parsing logic entirely, which lets it drop out
when nothing's using it (ala scripts/single.sh builds). That said, init.c
is currently using a "" option string and a USE_ macro taking advantage
of string concatenation may require a "" option config, so...

present (even for commands disabled in the config) to avoid undefined symbol errors referencing FLAG_ macros.

Don't #undefine TT in the CLEANUP blocks of generated/flags.h, and #ifdef
around the other TT definition. That way you can put a union at the start
of your GLOBALS() with the arguments filled out by option parsing, and then
have multiple main() functions with different argumetns and different
FLAG_x macros, while sharing infrastructure that's not under lib.

command line option groups, move len/dist tables to GLOBALS and calculate instead of including literal tables, collate enum and typedef, convert main to toybox option parsing.

Confirmed with him on IRC it's ok to use under toybox license, glued the files
together and hammered square peg into round hole, no other changes yet.

The original codepath checks if there is a VT available,
and if there isn't sets TERM to vt102 (unless TERM is set to something
other than "linux").
Otherwise, TERM is set to "linux" if it is not already set.
However, we can rely on getty/... to set TERM if "linux" is not suitable.
This has the benefit of dropping a slightly messy section.

* __GLIBC__ was checked unconditionally;
this made for a very messy build on musl.
* int fd in chvt is always initialized; GCC 3.4 does not recognize this.

-Don't panic on failure to write messages.
-Don't panic on failure to fork; sleep an extra second instead.
-s/defualt/default/g
-Inline a couple functions called once.
(Don't inline inittab_parsing because it is too large).

Partly because there's no supplied target string ala sprintf, and partly
because I can never remember what order the m and s go in.
