Abstract
|
| 14 |
========
|
| 15 |
|
| 16 |
Ebuilds that install mail delivery agents often need to know the default
|
| 17 |
location of users' mailbox. When the mailbox is of a maildir type, there is no
|
| 18 |
set standard what the name of the directory should be. The most popular
|
| 19 |
extensions are "Maildir", ".Maildir" and Gentoo has adopted its own ".maildir"
|
| 20 |
name.
|
| 21 |
|
| 22 |
This GLEP proposes a user-definable maildir location.
|
| 23 |
|
| 24 |
Motivation
|
| 25 |
==========
|
| 26 |
|
| 27 |
To provide the means to change the default location of a maildir, that is
|
| 28 |
currently hardcoded in ebuilds.
|
| 29 |
|
| 30 |
The ".maildir" name is not adequate for most situations.
|
| 31 |
|
| 32 |
- "Maildir" is the defacto standard name for maildir mailboxes.
|
| 33 |
|
| 34 |
- People transferring e-mail configuration from other systems prefer to keep
|
| 35 |
the original naming conventions.
|
| 36 |
|
| 37 |
- In a virtual hosting environment, having a hidden file in a directory
|
| 38 |
dedicated for e-mail delivery is not a plus.
|
| 39 |
|
| 40 |
- All postfix and qmail related documentation gives "Maildir" as an example
|
| 41 |
name.
|
| 42 |
|
| 43 |
Rationale
|
| 44 |
=========
|
| 45 |
|
| 46 |
The following comments were made in a discussion [#bugreport]_ on the Gentoo
|
| 47 |
bugzilla
|
| 48 |
|
| 49 |
- The default location should be specified in ``rc.conf``
|
| 50 |
|
| 51 |
- Preventing users from shooting themselves in the foot is not an issue
|
| 52 |
|
| 53 |
Implementation
|
| 54 |
==============
|
| 55 |
|
| 56 |
A ``maildir.eclass`` has been submitted to Bug 52076 [#bugreport]_.
|
| 57 |
|
| 58 |
Patches that implement features similar to this GLEP have already been
|
| 59 |
submitted to Bug 52076 [#bugreport]_.
|
| 60 |
|
| 61 |
MAILDIR variable
|
| 62 |
----------------
|
| 63 |
|
| 64 |
The default location for maildir delivery is specified by the ``$MAILDIR``
|
| 65 |
variable. This variable is specified in ``rc.conf``.
|
| 66 |
|
| 67 |
maildir.eclass
|
| 68 |
--------------
|
| 69 |
|
| 70 |
This eclass exports a ``$MAILDIR`` variable to the ebuilds that inherit it. If
|
| 71 |
``$MAILDIR`` has not been specified in ``rc.conf`` the eclass exports
|
| 72 |
``MAILDIR=.maildir`` for backwards compatibility reasons.
|
| 73 |
|
| 74 |
Patching ebuilds
|
| 75 |
----------------
|
| 76 |
|
| 77 |
Since most ebuilds that currently need to know what the maildir delivery
|
| 78 |
location is already take the default ``.maildir`` location into account when
|
| 79 |
installing, modifying ebuilds to implement this GLEP is as simple as
|
| 80 |
inheriting the ``maildir.eclass`` and substituting ``.maildir`` in the ebuild
|
| 81 |
with the ``$MAILDIR`` variable. Care should be taken, to also modify any
|
| 82 |
patches or scripts that are used by the ebuild, that already have ``.maildir``
|
| 83 |
hardcoded (vpopmail, exim).
|
| 84 |
|
| 85 |
Backwards Compatibility
|
| 86 |
=======================
|
| 87 |
|
| 88 |
The default location is ".maildir", unless it is overridden. This way, there
|
| 89 |
would be no backwards compatibility issues.
