[Bug 463015] Re: Both fat and ext[234] boot sectors present at once cause confusion

[Phillip Susi]

It looks like mke2fs does indeed zap the fat boot sector, so grub
correctly identifies it as ext2, at least as far back as lucid.  Since
this was originally reported in 2009, maybe older versions didn't do
this?  Seems we can mark this one as fixed.

Title:
  Both fat and ext[234] boot sectors present at once cause confusion

Status in “e2fsprogs” package in Ubuntu:

Bug description:
  Binary package hint: grub2

  grub-probe incorrectly identifies my ext3 partition as containing a
  fat file system.  This means it can't boot without manual tweaking.

  I suspect the problem is that my partition contains stale fat
  signatures... this is probably a common problem, as mke2fs often
  doesn't wipe old signatures.

  I attached first 8k of my file system for testing purposes.
