Log Message:
coreutils, gnuls: Update to 9.1

CHangelog:
* Noteworthy changes in release 9.1 (2022-04-15) [stable]

** Bug fixes

  chmod -R no longer exits with error status when encountering symlinks.
  All files would be processed correctly, but the exit status was incorrect.
  [bug introduced in coreutils-9.0]

  If 'cp -Z A B' checks B's status and some other process then removes B,
  cp no longer creates B with a too-generous SELinux security context
  before adjusting it to the correct value.
  [bug introduced in coreutils-8.17]

  'cp --preserve=ownership A B' no longer ignores the umask when creating B.
  Also, 'cp --preserve-xattr A B' is less likely to temporarily chmod u+w B.
  [bug introduced in coreutils-6.7]

  On macOS, 'cp A B' no longer miscopies when A is in an APFS file system
  and B is in some other file system.
  [bug introduced in coreutils-9.0]

  On macOS, fmt no longer corrupts multi-byte characters
  by misdetecting their component bytes as spaces.
  [This bug was present in "the beginning".]

  'id xyz' now uses the name 'xyz' to determine groups, instead of xyz's uid.
  [bug introduced in coreutils-8.22]

  'ls -v' and 'sort -V' no longer mishandle corner cases like "a..a" \ 
vs "a.+"
  or lines containing NULs.  Their behavior now matches the documentation
  for file names like ".m4" that consist entirely of an extension,
  and the documentation has been clarified for unusual cases.
  [bug introduced in coreutils-7.0]

  On macOS, 'mv A B' no longer fails with "Operation not supported"
  when A and B are in the same tmpfs file system.
  [bug introduced in coreutils-9.0]

  'mv -T --backup=numbered A B/' no longer miscalculates the backup number
  for B when A is a directory, possibly inflooping.
  [bug introduced in coreutils-6.3]

** Changes in behavior

  cat now uses the copy_file_range syscall if available, when doing
  simple copies between regular files.  This may be more efficient, by avoiding
  user space copies, and possibly employing copy offloading or reflinking.

  chown and chroot now warn about usages like "chown root.root f",
  which have the nonstandard and long-obsolete "." separator that
  causes problems on platforms where user names contain ".".
  Applications should use ":" instead of ".".

  cksum no longer allows abbreviated algorithm names,
  so that forward compatibility and robustness is improved.

  date +'%-N' now suppresses excess trailing digits, instead of always
  padding them with zeros to 9 digits.  It uses clock_getres and
  clock_gettime to infer the clock resolution.

  dd conv=fsync now synchronizes output even after a write error,
  and similarly for dd conv=fdatasync.

  dd now counts bytes instead of blocks if a block count ends in "B".
  For example, 'dd count=100KiB' now copies 100 KiB of data, not
  102,400 blocks of data.  The flags count_bytes, skip_bytes and
  seek_bytes are therefore obsolescent and are no longer documented,
  though they still work.

  ls no longer colors files with capabilities by default, as file-based
  capabilties are very rarely used, and lookup increases processing per file by
  about 30%.  It's best to use getcap [-r] to identify files with capabilities.

  ls no longer tries to automount files, reverting to the behavior
  before the statx() call was introduced in coreutils-8.32.

  stat no longer tries to automount files by default, reverting to the
  behavior before the statx() call was introduced in coreutils-8.32.
  Only `stat --cached=never` will continue to automount files.

  timeout --foreground --kill-after=... will now exit with status 137
  if the kill signal was sent, which is consistent with the behavior
  when the --foreground option is not specified.  This allows users to
  distinguish if the command was more forcefully terminated.

** New Features

  dd now supports the aliases iseek=N for skip=N, and oseek=N for seek=N,
  like FreeBSD and other operating systems.

  dircolors takes a new --print-ls-colors option to display LS_COLORS
  entries, on separate lines, colored according to the entry color code.

  dircolors will now also match COLORTERM in addition to TERM environment
  variables.  The default config will apply colors with any COLORTERM set.

** Improvements

  cp, mv, and install now use openat-like syscalls when copying to a directory.
  This avoids some race conditions and should be more efficient.

  On macOS, cp creates a copy-on-write clone if source and destination
  are regular files on the same APFS file system, the destination does
  not already exist, and cp is preserving mode and timestamps (e.g.,
  'cp -p', 'cp -a').

  The new 'date' option --resolution outputs the timestamp resolution.

  With conv=fdatasync or conv=fsync, dd status=progress now reports
  any extra final progress just before synchronizing output data,
  since synchronizing can take a long time.

  printf now supports printing the numeric value of multi-byte characters.

  sort --debug now diagnoses issues with --field-separator characters
  that conflict with characters possibly used in numbers.

  'tail -f file | filter' now exits on Solaris when filter exits.

  root invoked coreutils, that are built and run in single binary mode,
  now adjust /proc/$pid/cmdline to be more specific to the utility
  being run, rather than using the general "coreutils" binary name.

** Build-related

  AIX builds no longer fail because some library functions are not found.
