+      the problem is:
+      watch the output of 'perl -V' - at the bottom:
+      <screen>
+        Characteristics of this binary (from libperl):
+          Compile-time options: MULTIPLICITY USE_ITHREADS USE_LARGE_FILES PERL_IMPLICIT_CONTEXT
+          Built under linux
+          Compiled at Feb 17 2003 12:38:57
+          @INC:
+            /etc/perl
+            /usr/local/lib/perl/5.8.0

+
+      The bad one is the "old" shared object coming with Time::HiRes for perl-5.6.1 living at
+      /usr/lib/perl5/auto/Time/HiRes/HiRes.so.
+      
+      We have these options:
+        1. delete this stuff
+        2. put a better version at '.'
+        3. place line '/usr/lib/perl/5.8.0' above of '/usr/lib/perl5'
+        4. copy stuff from '/usr/lib/perl/5.8.0' to '/usr/lib/perl5'
+      
+      Hmmm.....
+        I think i'll choose option 1.:
+        x rm -rf /usr/lib/perl5/auto/Time/HiRes
+        (or if you don't wanna be as brute-force)
+        x cd /usr/lib/perl5/auto/Time
+        x mv HiRes HiRes.old
+        
+    => let's try again:      
+      x /etc/init.d/amavis-milter restart
+        Time::HiRes object version 1.42 does not match bootstrap parameter 01.20 at /usr/lib/perl/5.8.0/DynaLoader.pm line 245.
+
+    => ahhh...  (also testable via 'perl -MTime::HiRes')
+      x dpkg --force-depends -r libtime-hires-perl
+      => my fault! ;-)
+
+  => so, everything works fine now....
+      x /etc/init.d/amavis-milter restart
+    
+o BER.pm:  BER (Basic Encoding Rules) encoding and decoding.
+
+o use a common [[http://razor.sourceforge.net/artistic.html|"Artistic License"]]?
+
+o use pdumpfs!
+
+o what we build seems similar to Torque <-> Maven  (Tangram|XyZ+Data::Storage <-> nfo-libs|rap)
+
+o write meta-documentation about why it's required to lift version-numbers of debian-packages
+  -> Why dpkg-liftversion?
+  1. yakka: libxml2!!!
+  2. amavis-milter: razor-1-branch-required
+
+o installing pdumpfs as system-wide backup-system:
+  x mkdir -p /home/service/virtual/pdumpfs/var/data
+  x mkdir -p /home/service/virtual/pdumpfs/var/log
+  x cd /usr/local/bin
+  x ln -s /home/service/virtual/pdumpfs/backup .
+
+o feature: BrowsableBackup:
+  o missing: authentication via LDAP....
+
+o make up toolpack from shortcuts/*, dispatchmail, backup (->pdumpfs), etc...
+  ->packages.service.netfrag.org
+  -->/usr/local/bin
+  
+o one account - three services:
+  o wiki
+  o news
+  o backup
+  (o ssh) (not-a-must)
+
+o dpkg-modcontrol!!!
+
+o robinson - purge package dependencies from .deb- or .rpm-packages
+  can alien do that?
+
+o rsync working: view from the server-side:
+ 3968 ?        R      0:40 rsync --server --sender -vulogDtprz . /home/service/backup/
+
+x finally: we have a backup-system!
+  - built on top of pdumpfs (ruby!), gets triggered by cron through shortcut-script 'backup'
+  - backs up:
+    x /home/*   (except /home/service)
+    x /data/bin  (approx. 9.2M)
+    x /data/libs  (approx. 1.7M)
+    x /data/opt  (approx. 27M)
+    o /data/var  (approx. 104M)
+      o mysql-db
+      o news-spool
+    o /data/www  (approx. 126M)
+      x /data/www/virtual/lashlarue  (approx. 28M)
+      x /data/www/virtual/netfrag  (approx. 68M)
+      x /data/www/virtual/wac  (approx. 4M)
+  o productive backup should go to /var/pdumpfs (similar to /var/backup) instead of /home/service/virtual/pdumpfs!!!
+  o prevent recursive backups (what happens if the backup directory itself would be specified to backup???)
+  => #> crontab -e
+        adding line: 03 03 * * * bash /home/service/virtual/agent/backup_all
+  o limit size of files that are backuped without user-request!?! (2MB, 10MB, 100MB, 1G)
+
+o establish logfile-rotation with logrotate!!!
+  #> cd /data/www/virtual/lashlarue/log
+  #> gzip access_log
+  #> gzip error_log
+
+o more todos:
+  1. clean more diskspace
+    How to find files larger than, hmm, let's say: 512MB?
+    use 'dus'! [Disk Usage Sorter]
+    http://marginalhacks.com/bin/dus
+    x now disk-usage-stats are prepared to be generated at service.netfrag.org (dus/fbf)
+    o /home/uml/skels aufräumen!
+  2. draw more diagrams
+  3. let 'monit' monitor our umls
+    together with heartbeat!
+  4. make more backups
+
+o look in /var/log/syslog after crash! (other logfiles?)
+
