# The OS InitRD ships with a minimal set of firmware that's required
# for the supported Hardware Models, but we don't ship an inventory
# file.  This is because not all Hardware Models require firmware
# (in particular 32bit ARM doesn't for the supported Hardware Models
# without externally connected peripherals).
# Additionally the firmware that *is* included may not be loaded
# on the Hardware Model you're using - e.g. the firmware for the Pinebook Pro's
# LCD panel is never loaded on the Raspberry Pi, yet it's included
# within the generic OS InitRD so that it's available for the Pinebook.
# Supplying a default inventory in this case would always cause a mismatch
# between the running OS and the OS InitRD when os-initrd-mgr is first
# run.
# This is why we don't ship an inventory cache within the Kernel package.
#
# However, we do need to delete any existing inventories because the
# newly placed OS InitRD will not contain any extra firmware/local user
# customisations that may have been incorporated by os-initrd-mgr.
# Deleting this inventory cache will enable os-initrd-mgr to re-scan the
# system and re-incorporate any extra firmware/local customisations
# once the Kernel package upgrade completes (i.e. now!)
#
# Inventory caches from the previous invocations of os-initrd-mgr are
# now null and void.
# Firmware inventory cache:
rm -f boot/.os-initrd-fw-inventory
# Kernel module inventory cache (used for --sync-loaded-kmods)
# This contains the Kernel module file name and a hash to use for comparison
# (to know whether to refresh the modules when re-packing the OSInitRD)
rm -f boot/.os-initrd-kmod-inventory
# List of the loaded Kernel module names:
# (used for --sync-loaded-kmods and --modprobe-synced-kmods)
rm -f boot/.os-initrd-kmod-names-inventory

# Local customisations inventory cache:
rm -f boot/.os-initrd-custs-inventory

# Short-term migration of config file to /etc:
# To be removed after a few releaes.
