[PATCH 00/11] This is an implementation of new wic subcommand 'wic cp'.

[Ed Bartosh]

Hi,

'wic cp' command copies files and directories to the vfat partition of the wic image.

Here are couple of examples:

Copy file to the root directory of the vfat partition:
    $ wic cp test.wks tmp/deploy/images/qemux86-64/core-image-minimal-qemux86-64.wic:1
    $ wic ls tmp/deploy/images/qemux86-64/core-image-minimal-qemux86-64.wic:1
        Volume in drive : is boot
         Volume Serial Number is DB4C-FD4C
        Directory for ::/

        efi          <DIR>     2017-05-24  18:15
        loader       <DIR>     2017-05-24  18:15
        startup  nsh        26 2017-05-24  18:15
        vmlinuz        6926384 2017-05-24  18:15
        test     wks       628 2017-05-24  21:22
                5 files           6 927 038 bytes
                                 15 677 440 bytes free

Copy directory to the efi subdirectory of the vfat partition:
   $ wic cp test tmp/deploy/images/qemux86-64/core-image-minimal-qemux86-64.wic:1/efi/
   $ wic ls tmp/deploy/images/qemux86-64/core-image-minimal-qemux86-64.wic:1/eti/
       Volume in drive : is boot
        Volume Serial Number is DB4C-FD4C
       Directory for ::/efi

       .            <DIR>     2017-05-24  18:15
       ..           <DIR>     2017-05-24  18:15
       boot         <DIR>     2017-05-24  18:15
       test         <DIR>     2017-05-24  21:27
               4 files                   0 bytes
                                15 675 392 bytes free


The patchset also contains fixes for sparse_copy bugs discuvered in the
process of working on 'wic cp' functionality.

It also contains test case for 'wic cp' command.

The following changes since commit ae4b01e75618030f3fa0a592c6dffddb2fdab3b5:

[PATCH 07/11] filemap: check if dest is written for every block

[Ed Bartosh]

If lenght parameter is provided to sparse_copy call
it's mandatory to check if the output file is fully
written after reading unmapped block from input file.

If it's not done then sparse_copy can write more data
than specified length.

to copy changed partition back into wic image.
