The "noprefixroute" option suppresses automatic generation of a routing
table entry based on the interface's ip address.
The ifa_flags field has only 8 bit. If higher bits are set,
rta_tb[IFA_FLAGS] has to be used instead.

With bash's read builtin it is possible to read from a file (e.g.
device-tree) until the first '\0' character:
IFS= read -r -d '' VARIABLE < file
In busybox ash the -d extension is also implemented, but checking the
read character for '\0' has to be performed after comparing with the
delimiter.

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.

odds with common layouts that have some of
bin/lib/lib32/lib64 symlinked.

On Alpine, some users use /dev/null as a home directory. When removing
such a user with `deluser --remove-home` this causes the /dev/null
device file to be removed which is undesirable. To prevent this pitfall,
check if the home directory specified for the user is an actual
directory (or a symlink to a directory).
Implementations of similar tools for other operating systems also
implement such checks. For instance, the OpenBSD rmuser(1)
implementation [0].

Commit d1b75e184 (httpd: permit non-default home directory with NOMMU
enabled) only works when used with the '-f' (foreground) option.
When '-f' isn't specified and NOMMU is enabled bb_daemonize_or_rexec()
is called to daemonize the server. Since the server process has been
re-execed the previous patch results in the xchdir() not being called.
Fix this by resetting the re_execed variable in this case.

Prior to the patch, both -f and --first-only are in all cases either
no-op or ignored.
Without --tabs, --first-only is the default so specifying it is a no-op.
With --tabs, --all is implied, and --first-only is intended to reset this.

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.

Since commit 7eb8eecbb (ash: eval: Add assignment built-in support
again) building BusyBox with the 'command' built-in disabled fails.
parse_command_args() only needs to be called when the 'command'
built-in is run. Which it won't be if it's disabled.
v2: Avoiding infinite loops is good, too. Thanks, Harald van Dijk.
