  • Download Debian Linux kernel and initrd files for all Debian distributions (Stable : Stretch; Testing : Buster; oldStable : Jessie; oldoldStable : Wheezy; Unstable : Sid) and for i386 and amd64 architectures.
  • Offer an example menu file to use with a TFTP server (default_path/installer/debian/menu.cfg.example).

Debian late_command

Description

Some useful configurations after a Debian installation :

  • Smarter log management (mainly for rotation and old logs).
    • Move rsyslog default configuration to two files (/etc/rsyslog.conf and /etc/rsyslog.d/99syslog.conf).
    • logrotate now rotate logs to specific directories (such as /var/log/syslog.d, /var/log/mail/,…) instead of /var/log/.
    • Create these new directories.
  • Remove some useless packages (nfs, tasksel,…).
  • Permit root SSH login with password (no standard user…).
  • …

Specific to Debian Jessie and older :

  • Smarter rsyslog (more directories and less files in /var/log).
    • 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

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

download_diag_tools.sh

download_clonezilla.sh

  • Download PXE files for Clonezilla live from OSDN. A Sourceforge repository is also available but…; see the Clonezilla download page for more informations.
  • Download for both amd64 and i686.
  • Make a example configuration file.
  • More informations on the Clonezilla website.

Update

The netboot's installers, at least for Debian, need to be update after each point realease. Just think about it if you got any issue during any installation from PXE.

  • Debian : sudo ./scripts/download_debian.sh
  • Debian's initrd with additionnals firmwares : sudo ./scripts/make_debian_initrd_with_firmware.sh
  • Ubuntu : sudo ./scripts/download_ubuntu.sh

Some tools depends of a static version in their script. So this is the list i check to got their new version :
