SI_Parameters
See manuals systemimager.cmdline(7) and dracut.cmdline(7) for detailed descriptions.
__Note: not all parameters are available depending on the way you specify them. si. is used on PXE cmdline.
Shell variable can be used in file specified by si.config or in local.cfg. Some of them can be updated in pre-install main-install and post-install scripts. Depending of the imaging progress, updating some variables can be a non-sense (changing DL_PROTOCOL has no meaning except in local.cfg, changing IMAGENAME in post-install has no meaning either for instance) Parameters are stored in /tmp/variables.txt and are accessible to pre-install main-install and post-install scripts during imaging.
- force a debug shell at specified breakpoint. you can have more than one si.break= parameter
This complement the rd.break from dracut (man dracut.cmdline for detailed list).
The break occurs just before specified step would start.
Possible values:
- parse-localcfg
- network-infos
- ping
- download-scripts
- monitor
- deploy
- pre-install
- prepare-disks
- main-install
- download-image
- extract-image
- install-overrides
- install-configs
- boot-loader
- post-install
- se-linux
- umount-client
- terminate-transfer
- finished
- enable/disable debug messages.
- Shell variable: $DEBUG
- imaging config file. overrides cmdline variables
- Shell variable: $SIS_CONFIG
- it defines the image name
- Shell variable: $IMAGENAME
- it defines the main install script name. Imager will look for $SCRIPTNAME, $SCRIPTNAME.sh, $SCRIPTNAME.master
- Shell variable: $SCRIPTNAME
- it defines how disk(s) must be initialized. Imager will look for $DISKS_LAYOUT and $DISKS_LAYOUT.xml
- Shell variable: $DISKS_LAYOUT
- man systemimager.disks-lauyout(7) for xml file format description.
- it defines the network interface(s) configuration (including aliases, bonding, ...). Imager will look for $NETWORK_CONFIG and $NETWORK_CONFIG.xml
- Shell variable: $NETWORK_CONFIG
- man systemimager.network-config(7) for xml file format description.
- it defines the download protocol to use when imaging. imager tries do guess it and defaults to rsync
- Shell variable: $DL_PROTOCOL
- points to server which listen for client console log output.
- Shell variable: $MONITOR_SERVER
- tells imager if conole messgaes must be sent to systemimager monitor (so si_monitortk can display them remotely)
- Shell variable: $MONITOR_CONSOLE
- tells imager if it should try to search for a local.cfg file
- shell variable: $SKIP_LOCAL_CFG
- tells imager where to fetch image
- Shell variable: $IMAGESERVER
- tells imager what is the remote syslog server port is.
- Shell variable: $LOG_SERVER_PORT
- tells imager if it needs to start ssh client (tunnel to image server)
- Shell variable: $SSH
- tells imager the ssh URL needed to fetch the image.
- If set, si.ssh-client is forced to "y" and si.dl-protocol is set to ssh if not yet defined.
- shell variable: $SSH_DOWNLOAD_URL
- tells imager to start an ssh server while imaging so you can connect remotely from server (need explanation on how to login)
- Shell variable: $SSHD
- tells imager which username should be used to create the ssh tunnel.
- Shell variable: $SSH_USER
- tells imager the flathrower path.
- if si.dl-protocol is not set, set DL_PROTOCOL to flametrower
- Shell variable: $FLAMETHROWER_DIRECTORY_PORTBASE
- shell variable: $TMPFS_STAGING
- tells imager what terminal type for imaged client console it should use
- sell variable: $TERM
- tells to imager to force a SE Linux relabel after imaging or at next boot.
- Shell variable: $SEL_RELABEL
si.post-action (defaults to reboot. Possible values: shell, reboot, shutdown, kexec, poweroff, directboot)
- tells imager what to do when job is done.
- shell: drop a shell after imaging
- directboot: if imager kernel has matching modules in /sysroot/lib/modules/${uname -r}/ then it just continue boot like a normal boot without rebooting, otherwize it'll reboot.
- shutdown or poweroff: stop the system
- Shell variable: $SI_POST_ACTION
