Details about issue

Replacing a file in a mount with the --in-place option of the sed command results in Permission denied.

I prepare a 1002 byte file and execute the sed command as shown below, an error will occur.

$ stat testfile
    File: ‘testfile’
    Size: 1002            Blocks: 2          IO Block: 4096   regular file
