Driver Update Disk Handling
|
||
|
|
|
||
|
|
anaconda-dracut takes advantage of dracut's hooks in order to load driver
|
||
|
|
modules before the rest of the installer is executed.
|
||
|
|
|
||
|
|
|
||
|
|
cmdline hook
|
||
|
|
parse-anaconda-dd.sh
|
||
|
|
parses the inst.dd/dd arguments for URIs and saves all of them into $dd_args
|
||
|
|
and calls set_neednet if network is needed to retrieve a driver rpm
|
||
|
|
The files will be downloaded when the network device online hook is executed.
|
||
|
|
|
||
|
|
initqueue/online
|
||
|
|
fetch-driver-net.sh
|
||
|
|
If URLs are passed to inst.dd they are all downloaded into /tmp/DD-net/
|
||
|
|
|
||
|
|
pre-trigger hook
|
||
|
|
driver-updates.sh
|
||
|
|
Looks for devices labeled OEMDRV and starts the systemd service for the UI
|
||
|
|
Also saves the initial state of the module list and uses udev to trigger
|
||
|
|
loading of existing modules.
|
||
|
|
|
||
|
|
pre-pivot hook
|
||
|
|
driver-updates-net.sh
|
||
|
|
Check for network downloaded driver rpms and start the systemd service to
|
||
|
|
load the drivers.
|
||
|
|
|
||
|
|
anaconda-depmod.sh
|
||
|
|
If any drivers were installed or downloaded run depmod on the $NEWROOT
|
||
|
|
|
||
|
|
|
||
|
|
Systemd Services
|
||
|
|
driver-updates@.service and driver-updates-net@.service
|
||
|
|
These services launch the driver update UI (/bin/driver-updates). The -net
|
||
|
|
version passes the path to the rpm's that have been downloaded from the
|
||
|
|
network. They handle connecting the tty so that the user can select drivers
|
||
|
|
if inst.dd has been passed on the cmdline.
|
||
|
|
|
||
|
|
|
||
|
|
driver-updates
|
||
|
|
This searches disks labeled OEMDRV for driver update repositories and
|
||
|
|
optionally lets the user pick individual drivers. It will also search
|
||
|
|
unlabeled devices if they are passed on the kernel cmdline with
|
||
|
|
inst.dd=/dev/sdb2
|
||
|
|
|
||
|
|
Pass it the path to a directory of rpms (eg. downloaded from the
|
||
|
|
network) and it will install them before checking for additional OEMDRV
|
||
|
|
labeled devices.
|
||
|
|
|
||
|
|
Pass inst.dd with no parameters and it will prompt the user for specific
|
||
|
|
drivers to load using a simple text user interface.
