In busybox-w32 the shell option '-l' sets HOME to the user's
home directory, as determined by a call to GetUserProfileDirectory().
This is differs from how shells work on Unix, where HOME is usually
set by login(1).
Allow the user to override this behaviour by setting HOME before
starting the shell. If HOME isn't set or contains an empty string
the previous behaviour applies. If HOME is set to a non-empty string
the user should ensure that it represents a valid absolute path.

Commit e6238530e (cpio: code shrink with !FEATURE_EXTRA_FILE_DATA)
broke the POSIX build by incorrectly excluding chunks of code.
|

Commit 96a647690 (ash: prevent issue with ctrl-c and echo in loop)
attempted to fix the problem that interrupting a loop like:
while true; do echo hello; done
caused the shell to exit. However, it wasn't completely effective
and it only applied to echo and printf, not other builtins.
Revert 96a647690 and instead don't call raise_interrupt() from
crtl_handler() for the foreground interactive shell.

busybox-w32 tries to display the ownership of files by comparing
the security identifier (SID) of the current user with that of the
file on disk. For filesystems that don't support SIDs this resulted
in files being listed as owned by root.
It appears that filesystems without support for file ownership
return a null SID. In such cases pretend the file belongs to the
current user.

There seems to be a bug in UCRT such that if a process has been
started by passing a non-NULL environment block to CreateProcess()
any subsequent call to spawnve() with a non-NULL environment pointer
results in a crash.
Commit 5b48ca53b (win32: pass NULL to spawnve, not environ) fixed
the problem in busybox-w32 for those cases where a NULL environment
pointer was sufficient. It didn't handle the case where the shell
passes a modified environment to its child.
All calls to spawnve() in the shell occur in a process which will
terminate whether or not the call succeeds. It therefore doesn't
matter if we mess with the environment of this process to allow
spawnve() to be passed a NULL environment pointer. Do this for
UCRT builds only.

The new --renumber-inodes option won't work if FEATURE_EXTRA_FILE_DATA
is disabled. Don't allow it to be selected in that case. In fact,
if FEATURE_EXTRA_FILE_DATA is disabled all the code to handle hardlinks
can be #ifdef'ed out.
The new --ignore-devno option need do nothing if FEATURE_EXTRA_FILE_DATA
is disabled, as in that case the device ids will already be zero.
It can still be selected, cpio will just always behave as though the
option was provided on the command line.
This doesn't affect the size of the default build.

Without FEATURE_EXTRA_FILE_DATA we don't have inode numbers to
match so -samefile won't work.

This can be faster on some CPUs.
On Skylake, evidently load latency from L1 (or store-to-load
forwarding in LSU) is fast enough to completely hide
memory reference latencies here.

This was missing in the previous attempt to fix it via [1]
This helps fix segfaults when compiling with clang ( seen on riscv64 )

The specification requires volume label to be space padded.
Latest fsck.vfat will remove the zero padded volume label
as invalid. See also:
https://github.com/dosfstools/dosfstools/issues/172
Make the default label also "NO NAME" which has the special meaning
that label is not set.
