+       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:
+. delete this stuff
+. put a better version at '.'
+. place line '/usr/lib/perl/5.8.0' above of '/usr/lib/perl5'
+. 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

+         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

+ 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?
+. yakka: libxml2!!!
+. amavis-milter: razor-1-branch-required
+ o installing pdumpfs as system-wide backup-system:

+   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:
+?        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)

+       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:
+   x clean more diskspace
+     - How to find files larger than, hmm, let's say: 512MB?
+       use 'dus'! [Disk Usage Sorter]
+       http://marginalhacks.com/bin/dus

+ o QoS for apt-get!!!  (http or ftp to x.debian.org or uni-erlangen.de (parse /etc/apt/sources.list!!!))
+ x jonen makes the words: integraded! yeah!
+ o Develop a metadata-model (preferably stored inside an LDAP-daemon),
+   which can hold information about Host <-> vHost <-> Service(s).
+   This would enhance the Host <-> [posix]Account model currently in development.
+   o Also associate the [posix]Accounts with an AddressBook! (AddressBook <-> ProprietaryAddressBook)
