Kjell,

I think you sent me this message and I replied to you but your service 
rejected my message, but since it is in german, I have no idea why. At 
that time I told you that Alpine can configure the location of /tmp. From 
the release notes:

    Unix _Alpine_ uses the following environment variables:
    TERM
           Tells _Alpine_ what kind of terminal is being used.
    DISPLAY
           Determines if _Alpine_ will try to display IMAGE attachments.
    TMPDIR, TMP, or TEMP
           Specifies location of temporary storage area, first one set wins
    SHELL
           If not set, default is /bin/sh
    MAILCAPS
           A semicolon delimited list of path names to mailcap files.

What I fail to understand is how is this something that Alpine has to work 
around? /tmp is not an invention of Alpine. How did you work around this 
that is so bad? (what was your script like?). In earnest, I fail to 
understand why Alpine has to do anything here because someone implements 
their own file system? What is the rationale? Why would ubuntu delete 
Alpine? I am sorry, I just do not see the problem here as an Alpine 
problem. If you could explain to me what you see the issue is, I would try 
to do something from Alpine to solve it, but I just do not see it. As far 
as I can tell, you can solve it by setting an environment variable. Does 
that solve the problem for you?
