        x build small systool script 'apt-get_remote.pl' which do a cronly 'apt-get --dry-run upgrade' and send output via mail
        o review 'apt-get_remote.pl'
          o what's about parsing some response for comand like installing some marked packages
-    FreeBSD(stable):
-      o read more about BSD package systems (pkg, cvsup)
-        x for simple package installation/de-installation use pkg
-          x install downloaded package:
-              :# pkg_add {package}-{version}.tgz
-          x install package via remote server(only if package is available as *latest*): 
-                pkg_add -r {package}.tgz
-        x using cvsup
-          x read http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/cvsup.html
-          x newbies could use cvsupit:
-              :# pkg_add -r cvsupit.tgz
-            - cvsupit will proberly ask you for the default values it
-              place at /etc/cvsupfile, which is used by cvsup
-            - after that it will start cvsup to update your system
-          x if /etc/cvsupfile already exists and you know what you do,
-             this command will update your system (maybe run it via cron...):
-              :# /usr/local/bin/cvsup -g -L 2 /etc/cvsupfile
-             where '-g' tells cvsup not to use a GUI, '-L 2' sets default output level to 2
-          x for available cvs tags, look at http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/cvs-tags.html
-      o whats about daemon start-stop scripts (like at linux: /etc/init.d/) ?
-      x configure and compile custom kernel:
-        x read http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-building.html
-        x create custom kernel conf-file
-          - cd usr/src/sys/i386/conf/
-          - copy default kenrnel GENERIC to eg MYKERNEL
-          - edit/modify MYKERNEL
-        x configure sources(really?)
-          - run /usr/sbin/config MYKERNEL
-        x build kernel
-          - cd ../../MYKERNEL
-          - make depend
-          - make
-          - make install
-      x use packet fiters (firewall):
-        x read http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/firewalls.html
-        x some options at the kernel have to be enabled:
-          - options IPFIREWALL
-           Compiles into the kernel the code for packet filtering.
-          - options IPFIREWALL_VERBOSE
-           Enables code to allow logging of packets through syslogd.
-           Without this option, even if you specify that packets should be logged in the filter rules, 
-           nothing will happen.
-          - options IPFIREWALL_VERBOSE_LIMIT=10
-           Limits the number of packets logged through syslogd on a per entry basis.
-           You may wish to use this option in hostile environments in which you want to log firewall activity,
-           but do not want to be open to a denial of service attack via syslog flooding.
-           When a chain entry reaches the packet limit specified, logging is turned off for that particular entry.
-           To resume logging, you will need to reset the associated counter using the ipfw(8) utility:
-                  :# ipfw zero 4500
-           Where 4500 is the chain entry you wish to continue logging.
-          - options IPFIREWALL_DEFAULT_TO_ACCEPT
-           This changes the default rule action from ``deny'' to ``allow''.
-           This avoids the possibility of locking yourself out if you happen to boot a kernel with IPFIREWALL support but have not configured your firewall yet.
-           It is also very useful if you often use ipfw(8) as a filter for specific problems as they arise.
-           Use with care though, as this opens up the firewall and changes the way it works.
-        x firewall is enabled at /etc/rc.conf (or /etc/rc.conf.local)
-             firewall_enabled = "YES"
-             firewall_type = "{firewall_type}"
-          x where {firewall_type} is either a case at /etc/rc.firewall (/etc/rc.firewall6 for ipv6)
-             or some custom file to read rules from.
-          x  Use firewall_type = "OPEN" for default policy 'OPEN' (allow all)
-          
-  - Backup:
-    x bacula (http://www.bacula.org)
-      x created debian package, cause we can't found any other
-        o create 'postinst' and 'prerm' scripts for saving configs on update, etc.
-      x tested network backup with Director, Storage Daemon and File Daemon(Client)
-         at different hosts, works great!
-      x tested backup to FileStorage, instead of using tapes drives
-         (if someone would like to sponsor some tape drive, you're more than welcome!)
-       notes:
-        x remember to use different 'LabelFormat' filename at each pool !
-        x use compression at 'FileSet' definition, where GZIP is equal to GZIP6, means compression-level 6 (1-9)
-         example:
-           # ====== snip FileSet ============
-           FileSet {
-             Name = "Full Set"
-             Include = signature=MD5 compression=GZIP { 
-             /home
-             }
-            Exclude = { *.o }
-          }
-           # ====== snip FileSet ============
