to avoid more problems

Puppet::Parser::Functions.autoloader.load(:create_resources) unless Puppet::Parser::Functions.autoloader.loaded?(:create_resources)
    Remove JBD compatibility layer 
    Add POSIX ACLs
    Add security xattr support (extended attributes for SELinux)
    Implement quota recovery 
    Periodic quota syncing 
    Implementation of local and global quota file handling
    Enable quota accounting on mount, disable on umount 
    Add a name indexed b-tree to directory inodes 
    Optimize inode allocation by remembering last group
    Optimize inode group allocation by recording last used group.
    Expose the file system state via debugfs 
    Add statistics for the checksum and ecc operations.
    Add CoW support. (reflink is unlimited inode-based (file based) writeable snapshots - very very useful for virtualization)
    Add ioctl for reflink. 
    Enable refcount tree support. 
    Always include ACL support 
    Implement allocation reservations, which reduces fragmentation significantly 
    Optimize punching-hole code, speeds up significantly some rare operations 
    Discontiguous block groups, necessary to improve some kind of allocations. It is a feature that marks an incompatible bit, ie, it makes a forward-compatible change
    Make nointr ("don't allow file operations to be interrupted") a default mount option 
    Allow huge (> 16 TiB) volumes to mount   (support for huge volumes)
    Add a mount option "coherency=*" to handle cluster coherency for O_DIRECT writes.
    Add new OCFS2_IOC_INFO ioctl: offers the none-privileged end-user a possibility to get filesys info gathering 
    Add support for heartbeat=global mount option (instead of having a heartbeat per filesystem you can now have a single heartbeat)
    SSD trimming support 
    Support for moving extents (preparation for defragmentation)

INTRODUCTION

WHO THE F.

PROBLEMS

1. Modules are not classes!

2. Too hard to use by non-developers

3. Poor interaction with third-party modules

4. Not versioned

5. Not pretty at all do down right f_ugly

REQUIREMENTS

1. Style Guidelines

2. Centralized parameters / settings

3. Fully Parameterized

4. Compatibility handling

5. Documentation

6. Releases

7. Puppet Compatibility

8. Integration: is uniquely identifiable

9. Easy to extend

SOLUTIONS

Check your code for formatting and style.

Documentation.

Releases

General / Initial module structure.
