Status of ext4 tools

["J.A. Magallón" <jamagallon@ono.com>]

Hi all...

I'm following the threads on ext4, but I have a couple questions, and
perhaps this can be a thread to bookmark with all the answers people
need... ;)

I have migrated some partitions to ext4 in several boxes (even my /home
on the One...and works fast), but...

- Where is the 'official' source for e4defrag ?
- I've read that e4defrag needs in-kernel support.
  Is it already in mainline ?
  From what kernel version ?
- I have seen that some distros refer to a package called 'e4fsprogs'.
  Does that thing exist ? Where ?
- Booting:
  - There seem to be patches for grub
    http://lists.openwall.net/linux-ext4/2008/11/19/8
    to boot ext4
  - and a Google SoC called 'grub4ext4'.
   -and there is also grub2 (ext4 support in svn).
  What would you recommend ?

That's what I miss to move completely to ext4 ;)

Apart from that, it works pretty fine.
The thing that most surprised me was that after the needed fsck, it had
converted files with contiguous blocks to big extents ;). Nice.

TIA
