debian postinst chowns install path

[mallman]

postinst-chown includes the line

chown ${{user}}:${{group}} ${{path}}

Yet all files underneath this path are owned by root. Shouldn't it be one way or the other? (All root or all daemon user?)

Nope. Read on the docs for exact default chown/chmod properties.

This is issue has been discussed in #170 , #174 , #178 and #210 :)

How mappings are handled

As this is still a documentation issue, I will explain the debian mappings here in a bit more detail and put them into the docs, when I got time.

You define a mapping (File, String). For linux this is done with

packageMapping( 
   file1 -> "/usr/share/file1",
   file2 -> "/usr/share/file2"
) withUser "youruser" withGroup "yourgroup"

With this definition two entries are generated in the postinst-chown, which are

chown youruser:yourgroup /usr/share/file1
chown youruser:yourgroup /usr/share/file2

If you want to own a complete directory by a specific user, user one of the MappingsHelper methods. A test build.sbt contains some examples.

Each directory/file in the mapping will then get a chown line.

The behavior I'm seeing is at odds with the documentation. The documentation says that /usr/share/<package> is owned by root. However, the packager sets the owner:group of /usr/share/<package> to <daemonUser>:<daemonGroup>. I have not modified the default mappings.

You are right, I'll fix this today

Awesome, thanks!
