As reported in the thread:
http://lists.xensource.com/archives/html/xen-users/2006-03/msg00721.html,
pygrub does not open ext2 file systems in partitioned images or sub
partitions on e.g. CentOS/RHEL 4, because e2fsprogs ext2fs_open does not
support an offset into the file to be opened.
With this patch, the error is correctly reported instead of a generic
"unable to open file" (and leaving the user searching in the dark).

if it can't figure out partitions and filesystems. This then makes it
balloon to absurd sizes. Make this only happen if you pass a debugging
flag

a) a couple of variables were referenced wrong
b) fix using arrow keys in the menu to act correctly
c) and look for grub config properly for /boot partition

to support having reading the boot loader config when you're using a
whole disk (eg, file:/root/disk.img,xvda,w) as opposed to just a
partition.
This reads the partition table in the MBR to find the active partition
and then passes that offset down into the filesystem reading code.

- pygrub/README provides information on packages needed to compile pygrub
- support reiserfs {2,3} filesystem
- dynamically build modules based on which filesystem libraries the
system has (proposed by Jeremy)
- pump up pygrub to version 0.2

Apply Nguyen's patch:
- extend filesystem abstraction by adding file_exist() method. this
method is used to check for existent of a file given its name. now
ext2fs implements this method.
- pygrub opens and parses /boot/grub/menu.lst or /boot/grub/grub.conf,
in that order.
- add /usr/lib/python to system path (see pygrub). without this
change, pygrub cannot find grub python package.
- remove few blank lines
