apache2_module breaks authz_svn module loading

[chuhn]

Hi y'all

Loading of the subversion Apache modules requires a strict load order:

1. mod_dav
2. mod_dav_svn
3. mod_authz_svn

At least on Debian Buster apache2_module 'authz_svn' breaks this load order by changing /etc/apache2/mods-available/authz_svn.load from

# Depends: dav_svn
<IfModule !mod_dav_svn.c>
    Include mods-enabled/dav_svn.load
</IfModule>
LoadModule authz_svn_module /usr/lib/apache2/modules/mod_authz_svn.so

to

LoadModule authz_svn_module /usr/lib/apache2/modules/mod_authz_svn.so

The load files will then be included in alphabetic order and apachectl configtest complains about:

apache2:
  Syntax error on line 146 of /etc/apache2/apache2.conf:
    Syntax error on line 1 of /etc/apache2/mods-enabled/authz_svn.load:
      Cannot load /usr/lib/apache2/modules/mod_authz_svn.so into server:
         /usr/lib/apache2/modules/mod_authz_svn.so: undefined symbol:
           dav_svn_get_repos_path2

What would be the best way to circumvent this issue? The contents of the .load file is thoroughly hard-coded in the apache2_module custom resource it seems …

Cheers
