Hi Abhilash,

I very much like the capability of mailman to create its own “var” directory 
structure - most open source systems require me to spend hours with strace 
trying to work out what directories and permission an application needs in what 
location - I’m heartily sick of having my time wasted like that so this is very 
refreshing functionality.

On the other hand it’s very confusing when a misconfiguration in the 
mailman.cfg results in a “var” directory being created in the current directory 
**which then gets picked up and used as the configuration**, so correcting your 
configuration in /etc/mailman.cfg then leads to a new problem, which is that 
your /etc/mailman.cfg is no longer being used *at all*.

I love the creation of the var directories by mailman but it feels like a bit 
of a hand grenade with a short fuse. Whilst I was setting up my configuration I 
ended up with var directories all over the file system, without any 
understanding of why they were there.  A trap for Mailman newbies.

Perhaps it’s worth considering making creation of the “var” directory structure 
could be the result of an explicit option rather than a default action.

thanks

Yes this is the default behavior when you don't specify the paths explicitly in 
your mailman.cfg  

You can see in the following that I have mailman.cfg in my /etc

You can also see that /etc/mailman.cfg defines locations for the various 
directories.

You can see that prior to running mailman info there is no “var” directory, but 
there is afterwards.

I’m curious to understand why it is doing this when apparently mailman is 
picking up the configuration file OK from /etc but ignoring its contents and 
then setting up a new var directory in the current directory.  Any ideas 
welcome.

blankontheme.zip  mailman  mailman.client  postorius  postorius_standalone

(venv2.7)ubuntu@server01:~$ grep _dir /etc/mailman.cfg
#var_dir: var
archive_dir              = /home/ubuntu/mailman/var/archives
bin_dir                  = /home/ubuntu/venv2.7/bin
data_dir                 = /home/ubuntu/mailman/var/data
etc_dir                  = /etc
ext_dir                  = /home/ubuntu/mailman/var/ext
list_data_dir            = /home/ubuntu/mailman/var/lists
lock_dir                 = /home/ubuntu/mailman/var/locks
log_dir                  = /home/ubuntu/mailman/var/logs
messages_dir             = /home/ubuntu/mailman/var/messages
queue_dir                = /home/ubuntu/mailman/var/queue
template_dir             = /home/ubuntu/mailman/var/templates
var_dir                  = /home/ubuntu/mailman/var

Where did you get this config from? Mailman supports INI-style config only. My 
bet is that mailman
is able to find your config file but is not able to parse it. What actually 
happens is that mailman
has predefined  paths for different scenarios which can be configured with 
layout variable in [mailman]
section inside your mailman.cfg. 

The default is `dev` layout which creates the `var` directory in the current 
directory.

You can either change the default `var_dir` in `dev` layout, below is a sample 
config for that:

```
[paths.dev]
var_dir : <dir_of_your_choice>
```

or you can use some other paths defined in src/mailman/config/mailman.cfg under 
[paths.local], [paths.master], [paths.fhs] and change the default layout in 
your mailman.cfg like this:

```
[mailman]
layout: local
```

Also my guess is that you can create your own path structure inside your 
mailman.cfg and use
that layout with mailman. How to create that can be seen in 
`src/mailman/config/mailman.cfg`.

thanks,
Abhilash Raj
