(Re-)Design of grml-live
None.
grml-live mainly executes the following main stages:
fai dirinstall: FAI (Fully Automatic Installation) does the chroot related work
mksquashfs: generate the compressed squashfs file which provides the chroot in compressed format
mkisofs: generates the ISO itself, based on the output by mksquashfs and some further bootmanger related stuff
This document describes the planned design for a re-implementation of grml-live in Python.

This document is work in progress. Seriously. |
The grml-live interface itself (no matter whether text based or a graphical interface) uses the provided mechanisms by lib-grml-live.
Helper Functions:
log(): log into syslog, /var/log/grml-live.log
console_info(): display information on plain console
usage(): display usage information
Validation:
check_permissions(): check for id == 0
check_diskspace(): check for enough free space(?)
check_programms(): check for all the necessary tools
Configuration handling:
parse_config_files(mainconfig=/etc/grml/grml-live.conf, localconfig=/etc/grml/grml-live.local): read /etc/grml/grml-live.local and /etc/grml/grml-live.conf
cmdline_opts(): parse commandline, overrides configuration from parse_config()
update_config_files(): write active configuration to configuration files (like /etc/grml/fai/apt/sources.list)
Installation of files:
install_chroot(): execute fai dirinstall
install_bootmanager(): install bootmanager (grub and/or isolinux)
install_initrd(): install initrd from chroot into booting area
install_kernel(): install kernel from chroot into booting area
install_addons(): install addons into booting area
install_bootsplash(): install bootsplash (image)
install_bootmessages(): install bootmessages
install_windows_binaries(): install windows (related) binaries
Create ISO:
create_squashfs(): execute mksquashfs
create_md5sums(): create md5sums
create_iso(): execute mkisofs
