BIG rework still in progress.
status:
- disk partitionning API finished.
- image transfer API finished. (support for rsync done, ssh, bittorrent,
flamethrower plugins not yet finished)
- autoinstall-lib.sh reworked
- systemimager-deploy-client.sh big rework. Now it will handle pre install
scripts and post install scripts and monitor reporting. all stuffs that have no
value added to be in imaging script.
=> Imaging script will be responsible to initialize disks and lay the image
down to it and run post install scripts. noting more.
- Still enhancing API to make it even more simple. (need to work on LVM api and
si_mkautoinstallscript rewrite)
A typical script can be:
# This master autoinstall script was created with SystemImager v4.5.1
# Using the following command:
# /usr/sbin/si_mkautoinstallscript -quiet --autodetect-disks -image
oscarimage_sda -force -ip-assignment static -post-install shell
# Load functions and variables left behind by the dracut logic scripts.
# autoinstall-lib loads systemimager-lib which loads /tmp/variables.txt.
# autoinstall-lib hosts funtions needed for imaging
# systemimager-lib hosts function needed for dracut logic (they are also
usefull here)
# /tmp/variables.txt hosts all relevant variables we need to keep track.
. /lib/autoinstall-lib.sh
# Uncomment the following line if you want system messages in GUI as well
sis_enable_system_msg
[ -z $IMAGENAME ] && IMAGENAME=oscarimage_sda
[ -z $OVERRIDES ] && OVERRIDES="oscarimage_sda $GROUP_OVERRIDES $HOSTNAME "
# Check to be sure this not run from a working machine

Objet : [PROVENANCE INTERNET] [Sisuite-devel] Reworking the partition creation
and also the script generator.
Hi,
I'm currently rewriting the script logic by integrating a partition
creation/edition into the systemimager dracut API (autoinstall-lib.sh)
This API will be able to handle natively diskfiles. The si_mkautoinstallscript
will be much simpler.
For this, I'll drop support of msdos partition types for now as it is becoming
widely deprecated and gpt is supported by most if not all currently maintained
OSes.
Aside that, the image transfert protocols have been put in separate API plugins
(one for rsync, one for bittorrent, .... ) This is easier for maintenance.
Regards,
