788      - probably because of perl-5.8.0?

791      solution:

794        x dpkg -i razor_1.20-1_all.deb
795         => depends on 'libtime-hires-perl', so:

800              Package perlapi-5.6.0 is not installed.
801              ;-( /)(%(/$%%&$
802        => removing dependencies about everything from razor1-package
803          x dpkg -x razor_1.20-1_all.deb razor

835    
836      x probably because of perl-5.8.0? yes!  --  is it fixed now? let's try...  (again)
837          x /etc/init.d/amavis-milter restart
838            no! same error as above!
839          the problem is:
840          watch the output of 'perl -V' - at the bottom:
841          <screen>
842            Characteristics of this binary (from libperl):
843              Compile-time options: MULTIPLICITY USE_ITHREADS USE_LARGE_FILES PERL_IMPLICIT_CONTEXT
844              Built under linux
845              Compiled at Feb 17 2003 12:38:57
846              @INC:
847                /etc/perl
848                /usr/local/lib/perl/5.8.0
849                /usr/local/share/perl/5.8.0
850                /usr/lib/perl5
851                /usr/share/perl5
852                /usr/lib/perl/5.8.0

854                /usr/local/lib/site_perl
855                .
856          </screen>
857    
858          The bad one is the "old" shared object coming with Time::HiRes for perl-5.6.1 living at
859          /usr/lib/perl5/auto/Time/HiRes/HiRes.so.
860          
861          We have these options:
862            1. delete this stuff
863            2. put a better version at '.'
864            3. place line '/usr/lib/perl/5.8.0' above of '/usr/lib/perl5'
865            4. copy stuff from '/usr/lib/perl/5.8.0' to '/usr/lib/perl5'
866          
867          Hmmm.....
868            I think i'll choose option 1.:
869            x rm -rf /usr/lib/perl5/auto/Time/HiRes
870            (or if you don't wanna be as brute-force)
871            x cd /usr/lib/perl5/auto/Time
872            x mv HiRes HiRes.old
873            
874        => let's try again:      
875          x /etc/init.d/amavis-milter restart
876            Time::HiRes object version 1.42 does not match bootstrap parameter 01.20 at /usr/lib/perl/5.8.0/DynaLoader.pm line 245.
877    
878        => ahhh...  (also testable via 'perl -MTime::HiRes')
879          x dpkg --force-depends -r libtime-hires-perl
880          => my fault! ;-)
881    
882      => so, everything works fine now....
883          x /etc/init.d/amavis-milter restart
884        
885    o BER.pm:  BER (Basic Encoding Rules) encoding and decoding.
886    
887    o use a common [[http://razor.sourceforge.net/artistic.html|"Artistic License"]]?
888    
889    o use pdumpfs!
890    
891    o what we build seems similar to Torque <-> Maven  (Tangram|XyZ+Data::Storage <-> nfo-libs|rap)
892    
893    o write meta-documentation about why it's required to lift version-numbers of debian-packages
894      -> Why dpkg-liftversion?
895      1. yakka: libxml2!!!
896      2. amavis-milter: razor-1-branch-required
897    
898    o installing pdumpfs as system-wide backup-system:
899      x mkdir -p /home/service/virtual/pdumpfs/var/data
900      x mkdir -p /home/service/virtual/pdumpfs/var/log
901      x cd /usr/local/bin
902      x ln -s /home/service/virtual/pdumpfs/backup .
903    
904    o feature: BrowsableBackup:
905      o missing: authentication via LDAP....
906    
907    o make up toolpack from shortcuts/*, dispatchmail, backup (->pdumpfs), etc...
908      ->packages.service.netfrag.org
909      -->/usr/local/bin
910      
911    o one account - three services:
912      o wiki
913      o news
914      o backup
915      (o ssh) (not-a-must)
916    
917    o dpkg-modcontrol!!!
918    
919    o robinson - purge package dependencies from .deb- or .rpm-packages
920      can alien do that?
921    
922    o rsync working: view from the server-side:
923     3968 ?        R      0:40 rsync --server --sender -vulogDtprz . /home/service/backup/
924    
925    x finally: we have a backup-system!
926      - built on top of pdumpfs (ruby!), gets triggered by cron through shortcut-script 'backup'
927      - backs up:
928        x /home/*   (except /home/service)
929        x /data/bin  (approx. 9.2M)
930        x /data/libs  (approx. 1.7M)
931        x /data/opt  (approx. 27M)
932        o /data/var  (approx. 104M)
933        o /data/www  (approx. 126M)
934          x /data/www/virtual/lashlarue  (approx. 28M)
935          x /data/www/virtual/netfrag  (approx. 68M)
936          x /data/www/virtual/wac  (approx. 4M)
937    
938    o establish logfile-rotation with logrotate!!!
939      #> cd /data/www/virtual/lashlarue/log
940      #> gzip access_log
941      #> gzip error_log
