  • Shorter configuration file and use more files from /etc/rsyslog.d/
  • Move log files to directory :
    • kern logs from /var/log/kern.log to /var/log/kernel/kernel.log
    • user logs from /var/log/user.log to /var/log/security/user.log
    • mail logs from /var/log/mail.… to /var/log/mail/mail.…
    • daemon logs from /var/log/daemon.log to /var/log/syslog/daemon.log
    • auth logs from /var/log/auth.log to /var/log/security/auth.log
    • lpr logs from/var/log/lpr.log to /var/log/lpr/lpr.log
    • cron logs from /var/log/cron.log to /var/log/cron/cron.log
    • localX logs from /var/log/localX.log to /var/log/syslog/localX.log
    • syslog logs from /var/log/syslog.log to /var/log/syslog/syslog.log
    • authpriv logs from … to /var/log/security/authpriv.log
• Smarter logrotate (add timestamp, move some old log files to the same directory,…).
• Remove some useless packages.
• Permit root SSH login with password (no standard user…).
• …

How-to use it

• First, make an archive of the script and directories :

cd scripts/ ;
tar czvf latecommand.tar.gz latecommand/

• Then, it can be use at the end of a Debian preseed file :

d-i preseed/late_command string in-target chsh -s /bin/zsh ; \
in-target /usr/bin/tftp ${IP.SRV.TFTP} -c get ${PATH/TO/TFTPD/ROOT}/scripts/latecommand.tar.gz /tmp/latecommand.tar.gz ; \
in-target tar xzf /tmp/latecommand.tar.gz -C /tmp/ ; \
in-target /bin/sh /tmp/latecommand/post.sh
