Why I did it To address error sometimes seen when running sonic-mgmt test_stress_routes.py::test_announce_withdraw_route on 720DT-48S How I did it Update boot0 logic to set platform specific varlog size for 720DT-48S How to verify it Verified that /var/log size increased and error is no longer observed when running test

# Aboot stage 0 boot script
|
|
#
|
|
# This boot0 script can be used in different scenario
|
|
# - Installation and boot from Aboot (manual or reboot on a new image)
|
|
# - EOS to SONiC fast-reboot (installation and kexec in EOS)
|
|
# - SONiC to SONiC fast-reboot (installation and kexec in SONiC)
|
|
#
|
|
# Use it this way:
|
|
# - swipath=path/to/swi install=true boot0
|
|
# - swipath=path/to/swi install=true force=true boot0
|
|
# - swipath=path/to/swi kexec=true boot0
|
|
#
|
|
# The logic defaults to the first scenario but providing extra environment variable
|
|
# will affect the behavior of the script.
|
|
# The list of variables is maintained here
|
|
# - KERNEL : relative path to the kernel to execute
|
|
# - INITRD : relative path to the initrd to load
|
|
# - CMDLINE : place to find the default kernel cmdline to use for the platform
|
|
# - VERBOSE : setting it to 1 will enable debug traces
|
|
#
|
|
# By default the boot0 script will behave for an Aboot based behavior.
|
|
# Options can be provided to only run some features of this script.
|
|
#
|
|
# Extra kernel parameters can be provided at runtime by the user by adding them
|
|
# into the kernel-params file.
|
|
#
|
|
# Secureboot of SONiC SWI images is also supported.
|
|
# In such cases, there will only be a partial install on the flash.
|
|
# SONiC will be mostly booting in RAM as a live operating system.
|
|
|
|
# All templated variables should be declared here
