785      - probably because of perl-5.8.0?
786

797              Package perlapi-5.6.0 is not installed.
798              ;-( /)(%(/$%%&$
799        => removing dependencies about everything from razor1-package
800          x dpkg -x razor_1.20-1_all.deb razor

832    
833      x probably because of perl-5.8.0? yes!  --  is it fixed now? let's try...  (again)
834          x /etc/init.d/amavis-milter restart
835            no! same error as above!
836          the problem is:
837          watch the output of 'perl -V' - at the bottom:
838          <screen>
839            Characteristics of this binary (from libperl):
840              Compile-time options: MULTIPLICITY USE_ITHREADS USE_LARGE_FILES PERL_IMPLICIT_CONTEXT
841              Built under linux
842              Compiled at Feb 17 2003 12:38:57
843              @INC:
844                /etc/perl
845                /usr/local/lib/perl/5.8.0
846                /usr/local/share/perl/5.8.0
847                /usr/lib/perl5
848                /usr/share/perl5
849                /usr/lib/perl/5.8.0

851                /usr/local/lib/site_perl
852                .
853          </screen>
854    
855          The bad one is the "old" shared object coming with Time::HiRes for perl-5.6.1 living at
856          /usr/lib/perl5/auto/Time/HiRes/HiRes.so.
857          
858          We have these options:
859            1. delete this stuff
860            2. put a better version at '.'
861            3. place line '/usr/lib/perl/5.8.0' above of '/usr/lib/perl5'
862            4. copy stuff from '/usr/lib/perl/5.8.0' to '/usr/lib/perl5'
863          
864          Hmmm.....
865            I think i'll choose option 1.:
866            x rm -rf /usr/lib/perl5/auto/Time/HiRes
867            (or if you don't wanna be as brute-force)
868            x cd /usr/lib/perl5/auto/Time
869            x mv HiRes HiRes.old
870            
871        => let's try again:      
872          x /etc/init.d/amavis-milter restart
873            Time::HiRes object version 1.42 does not match bootstrap parameter 01.20 at /usr/lib/perl/5.8.0/DynaLoader.pm line 245.
874    
875        => ahhh...  (also testable via 'perl -MTime::HiRes')
876          x dpkg --force-depends -r libtime-hires-perl
877          => my fault! ;-)
878    
879      => so, everything works fine now....
880          x /etc/init.d/amavis-milter restart
881        
882    o BER.pm:  BER (Basic Encoding Rules) encoding and decoding.
883    
884    o use a common [[http://razor.sourceforge.net/artistic.html|"Artistic License"]]?
885    
886    o use pdumpfs!
887    
888    o what we build seems similar to Torque <-> Maven  (Tangram|XyZ+Data::Storage <-> nfo-libs|rap)
889    
890    o write meta-documentation about why it's required to lift version-numbers of debian-packages
891      -> Why dpkg-liftversion?
892      1. yakka: libxml2!!!
893      2. amavis-milter: razor-1-branch-required
894    
895    o installing pdumpfs as system-wide backup-system:
896      x mkdir -p /home/service/virtual/pdumpfs/var/data
897      x mkdir -p /home/service/virtual/pdumpfs/var/log
898      x cd /usr/local/bin
899      x ln -s /home/service/virtual/pdumpfs/backup .
900    
901    o feature: BrowsableBackup:
902      o missing: authentication via LDAP....
903    
904    o make up toolpack from shortcuts/*, dispatchmail, backup (->pdumpfs), etc...
905      ->packages.service.netfrag.org
906      -->/usr/local/bin
907      
908    o one account - three services:
909      o wiki
910      o news
911      o backup
912      (o ssh) (not-a-must)
913    
914    o dpkg-modcontrol!!!
915    
916    o robinson - purge package dependencies from .deb- or .rpm-packages
917      can alien do that?
918    
919    o rsync working: view from the server-side:
920     3968 ?        R      0:40 rsync --server --sender -vulogDtprz . /home/service/backup/
921    
922    x finally: we have a backup-system!
923      - built on top of pdumpfs (ruby!), gets triggered by cron through shortcut-script 'backup'
924      - backs up:
925        x /home/*   (except /home/service)
926        x /data/bin  (approx. 9.2M)
927        x /data/libs  (approx. 1.7M)
928        x /data/opt  (approx. 27M)
929        o /data/var  (approx. 104M)
930        o /data/www  (approx. 244M)
931          x /data/www/virtual/lashlarue  (approx. 28M)
932          x /data/www/virtual/netfrag  (approx. 68M)
933          x /data/www/virtual/wac  (approx. 4M)
934    
935    o establish logfile-rotation with logrotate!!!
936      #> cd /data/www/virtual/lashlarue/log
937      #> gzip access_log
938      #> gzip error_log
