Why I did it Support to use symbol links in platform folder to reduce the image size. The current solution is to copy each lazy installation targets (xxx.deb files) to each of the folders in the platform folder. The size will keep growing when more and more packages added in the platform folder. For cisco-8000 as an example, the size will be up to 2G, while most of them are duplicate packages in the platform folder. How I did it Create a new folder in platform/common, all the deb packages are copied to the folder, any other folders where use the packages are the symbol links to the common folder. Why platform.tar? We have implemented a patch for it, see #10775, but the problem is the the onie use really old unzip version, cannot support the symbol links. The current solution is similar to the PR 10775, but make the platform folder into a tar package, which can be supported by onie. During the installation, the package.tar will be extracted to the original folder and removed.

# 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
