Re: [Xen-devel] XCP: pygrub missing ext4 support.

Well, which ever way we do it, either using the built in libfsimage
ext4 support, or upgrading e2fsprogs, we should choose one?
Well, when using libfsimage *non-e2fsprogs* implementation the ext4
support have to be added manually but when using e2fsprogs
implementation (i.e. the version linked with e2fsprogs) I recommend
upgrading your version of e2fsprogs to the newest/upstream version.

It currently doesn't because the libfsimage ext2fs-lib
module is linked
against libext2fs, which doesnt have ext4 support in XCP.
Instead, XCP should use the ext2fs module that comes
with libfsimage,
which has ext4 support.
Most new releases of distributions has it as their
default filesystem.
Most notably, Ubuntu 10.04
Also Fedora 12, Fedora 13, upcoming Debian 6.0 ("Squeeze") and
RHEL6.

Well, this is not the Xen issue here. We're having this fixed in
RHEL-5 by simply reinstalling the e2fsprogs package to the latest
one, although in case of RHEL-5 it's been renamed to e4fsprogs.
The simplest thing you can do about this is to reinstall the
e2fsprogs package on the host machine and it will be working fine
- at least it was when I did test it on RHEL-5 some time ago.
Simply put, reinstalling the e2fsprogs to the latest version will
do the job and allow ext4 functionality to pygrub.

An easy way for the build to use ext2fs instead of
ext2fs-lib, is to not
have ext2fs/ext2fs.h present.
Alternatively this patch hard codes it.
