Bug#358001: partman: please create ext3 file systems with online resize support

[Petter Reinholdtsen <pere@hungry.com>]

Version 1.38+1.39-WIP-2006.03.29-1 of e2fsprogs included support for
online (mounted) resizing of ext3 file systems, so now the default
tools support this feature.  mke2fs now support the config file
/etc/mke2fs.conf, and inserting the following will enable the online
resize feature on created file systems:

  [defaults]
        base_features = sparse_super,filetype,resize_inode

Note that ext2prepare is reported to corrupt the file system, so it
need to be used with caution until the problem is fixed.
