The flag disables termcap init/deinit of the terminal, which the applet
doesn't do anyway.

The behaviour introduced by commit 31c765081d ("watchdog: stop
watchdog first on startup") causes warnings in the kernel log when the
nowayout feature is enabled:
[ 16.212184] watchdog: watchdog0: nowayout prevents watchdog being stopped!
[ 16.212196] watchdog: watchdog0: watchdog did not stop!
The latter may also appear by itself in case the watchdog is of the
type that cannot be stopped once started (e.g. the common
always-running gpio_wdt kind).
These warnings can be somewhat ominous and distracting, so allow
configuring whether to use this open-write-close-open sequence rather
than just open. Also saves a bit of .text when disabled:
function old new delta
shutdown_on_signal 31 58 +27
watchdog_main 339 306 -33
shutdown_watchdog 34 - -34

(add/remove: 0/1 grow/shrink: 1/1 up/down: 27/-67) Total: -40 bytes
Make it default n:
- It's a workaround for one specific type of watchdog (and
that seems to be a defect in the kernel driver)
- Even when not enabled in busybox config, it can easily be
implemented outside busybox
- Code size
- Commit 31c765081d should be considered a regression for all the
boards that now end up with KERN_CRIT warnings in dmesg.
- The author of that commit said "This use case is evidently rare, so
if it is indeed causing problems for other people I'd OK then I
understand whatever needs to be done." in the v1 thread.

PLATFORM_LINUX is a hidden configuration option which is disabled by
default and enabled at over a hundred locations for features that are
deemed to be Linux specific.
The only effect of PLATFORM_LINUX is to control compilation of
libbb/match_fstype.c. This file is only needed by mount and umount.
Remove all references to PLATFORM_LINUX and compile match_fstype.c
if mount or umount is enabled.

Some editors (like vim) use renaming strategy to save file. That means
they save a file to some random name and then rename it to final
location. The advantage is that such save is atomic.
However, crontab -e holds open fd to the temporary file, meaning it
never sees the changes. The temporary file needs to be re-opened after
the editor terminates for the changes to properly save.

mim runs scripts from a specification file which can be thought
of as an extremely limited Makefile. Neither make variables nor
dependencies are supported. By default the file 'Mimfile' is read.
An example:
hello:
echo hello $1
clean:
rm -rf *
The command 'mim' or 'mim hello' will echo 'hello'. Unlike 'make'
arguments after the first are available to the script; they don't
specify additional targets.
mim isn't enabled by default. Enabling it increases the size of the
binary by about 500 bytes.
