## Description
Set of scripts to download and generate necessary files to allow differents GNU/Linux distributions to boot through the network.

## Scripts list

### download_debian.sh
The script will provide netboot installers for all Debian (>=Stable) for both **i386** and **amd64** :
  * Store the files to **/var/lib/tftpboot** (default).
  * Download Debian Linux kernel and initrd files for all Debian distributions (Stable : **Jessie**; Testing : **Stretch**; 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).

### download_ubuntu.sh

  * Store the files to **/var/lib/tftpboot** (default).
  * Download Ubuntu Linux kernel and initrd files for the two lasts Ubuntu distributions (LTS-16.04 : **Xenial**; 15.10 : **Wily**) and for **i386** and **amd64** architectures.
  * Make a symlink to access to the LTS (default_path/installer/ubuntu/lts) instead of it's codename.

### make_debian_initrd_with_firmware.sh
The script will provide Debian's netboot installers with **additionnals firmwares** for all Debian (>=Stable) for **amd64** only :

  * Extract initrd and firmwares packages to build a new initrd.

### Debian late_command

#### Description
Some useful configurations after a Debian installation :
  * 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__
  * 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
```

### download_diag_tools.sh
- The script will download some diagnostic tools :
  * memtest86 from [memtest86's official website][memtest official website].
  * GParted Live from the [sourceforge's repository][gparted sourceforge] for both amd64 and i686. See the [official documentation][gparted pxe] for more informations.
- Provide an example of configuration file.

### download_clonezilla.sh
* Download PXE files for Clonezilla live from [OSDN][OSDN url]. A Sourceforge repository is also available but…; see the [Clonezilla download page][clonezilla download] for more informations.
