[Bug 935480] Re: mkdosfs refuses to run on /dev/loop0p1

[Jan Claeys]

Actually, on modern unix systems "rm -rf /" will refuse to delete
anything (unless you add a special option, like " --no-preserve-root" in
GNU rm).

This follows POSIX.1-2008/SUSv4[1]:

| The rm utility shall remove the directory entry specified by each file argument.
| 
| If [...] or if an operand resolves to the root directory, rm shall write a diagnostic
| message to standard error and do nothing more with such operands.

Title:
  mkdosfs refuses to run on /dev/loop0p1

Status in “dosfstools” package in Ubuntu:
  Confirmed

Bug description:
  psusi at faldara:~$ sudo mkdosfs /dev/loop0p1
  mkdosfs 3.0.9 (31 Jan 2010)
  mkdosfs: Device partition expected, not making filesystem on entire device '/dev/loop0p1' (use -I to override)

  Obviously this is wrong since loop0p1 IS a partition.  Oddly, it does
  not complain on loop0p2.
