Bakunin's replacement code in post#4 is portable but still creates a new inode for the input file ("/path/to/file")
This not only denotes a repair of the original owner/group/permissions, it will make a previously hard-linked file stand-alone, and this damage cannot be repaired.
Also GNU sed -i (and perl -i) cannot preserve the original linkage.
If we are going for a real improvement then we avoid the mv command!
The cp command preserves the original inode (owner/group/permissions and linkage) - only the timestamp changes, and that's pretty correct.

diskowner
diskowner(1M)diskowner(1M)NAME
diskowner - retrieve the owner of a storage device
SYNOPSIS
path
DESCRIPTION
The command is used to retrieve the subsystem, if any, which is using the specified path. The command is intended to help prevent users
from overwriting storage that is already in use. The command will print out the owner of the path, or if no owner was found. A storage
device is considered owned by a subsystem if it has been formatted by that subsystem. For example, if a disk contains a VxFS filesystem,
but is not mounted or in use, it is still considered owned by the VxFS subsystem.
If the path specified is invalid or inaccessible, an error message will be printed.
Options and Arguments
The command recognizes the following options and arguments:
path The path name to the storage device. The path may be a symbolic link, as long as it points to a storage device, such as a file,
disk, or logical volume.
List all the owners of the specified path, seperated by commas
Produce a compact output that is easily parsed by other scripts and
programs. When used with option, displays all the owners seperated by dots This format is described in the section below.
Output from diskowner
displays the following possible output:
owner The owner of the given path. owner can be one of the following:
The path is not owned by any known subsystem.
The path is part of an LVM volume group.
The path is part of a VxVM volume group.
The path has a VxFS filesystem on it.
The path has a HFS filesystem on it.
The path is being used as a swap device.
The path is being used as a dump device.
The path is part of an Oracle database.
The path has EFI partitions on it.
message An error message displayed when the given path is invalid or inaccessible.
Compact Listing

RETURN VALUE
Upon completion, returns one of the following values:
The path is not owned (the owner is
The path is already owned by a subsystem.
The path does not exist.
Invalid options or library version incompatible.
The path cannot be opened due to an I/O error.
The path cannot be opened due to insufficient permissions.
The path format is invalid.
