Fix the issue of incorrectly skipping the convertfs hook when fast-reboot from EOS, by adding an extra kernel cmdline param "prev_os" to differentiate fast-reboot from EOS and from SONiC.
This is because we still do disk conversion for fast reboot from eos to sonic, like format the disk.
when device disk is small, do not unzip dockerfs.tar.gz on disk.
keep the tar file on the disk, unzip to tmpfs in the initrd phase.
enabled this for 7050-qx32

* Update arista drivers submodule
* Ignore the possible timestamp warning in tar extraction
* Add verbosity toggle to boot0
Console logging is slow because of the 9600 baud rate.
Some time can be saved by decreasing the console verbosity.
* Add hook mechanism in boot0.
Support additional features in boot0 via hooks.
Hooks are unpacked and executed at post-install or pre-exec time.
* Fix 7170 sensors.conf file
Fix critical temperature settings for MAX6658 sensors
* Fix the random swap of storage devices
For arista 7050 switches running with linux 4.9, it is likely the device
name of flash drive (/dev/sda) and usb (/dev/sdb) randomly swap in kernel
booting, depending on which one is ready first. It breaks the expectation
that flash will be mounted as root by setting root=/dev/sda1. This patch
will correct ROOT to flash device refering to the path under block_flash.
* Fix 7170 fancontrol
* Do not remove aquota.user file in boot0
This file is a filesystem protected file used by EOS.
It can be simply removed and will make the SONiC installation failed if
not skipped.
Flashes used for the 7050QX-32 and 7050QX-32S have a fw issue.
The best option to solve the problem is to upgrade to a newer firmware.
However this can only be done while in memory and take 10 seconds.
Adding an upgrade mechanism is possible but would need more
consideration as flashing the firmware and reformating the flash will
exceed the fast-reboot requirements.
A quick mitigation is to align the ext4 partition that we create on
these vfat based system on a 4k boundary.
Here we chose 1M instead but it's the same.
Newer version of sfdisk do this automatically but the one in SONiC
today doesn't have this behavior.
This workaround will only reduce the pace of the flash health
degradation. The only long term fix is to flash the firmware.
* Update sensors.conf for 7050QX-32 and 7050QX-32S
These two platforms were using a previous version of a kernel driver.
The new one names the i2c buses differently.
We therefore need to rename them here.
* Fix the default minigraph for the 7050QX-32S
The interface offset is invalid which makes sonic-cfggen generate an
invalid config_db.jon in rc.local.
This config then silently makes orchagent/syncd fail.
* Use the partition on which sonic-aboot.swi is
Instead of always assuming /mnt/flash, use the partition where the image
to be installed lies.
This allow for the image to be on any partition.
* Support OS9 -> SONiC fast-reboot migration
* Address review comments. Update NOS mac in EEPROM and net.rules for eth0
* Address review comments. Update sonic-platform-modules-dell to fac81d...
* Fix script for POSIX compliance
* Reduce SONiC migration partition from 8G to 1G.
* Changes to create 1G partition with ability to resize post migration.
* Remove redundant changes in varlog
* Use findfs to interpret root. Move resize in case cmdline params are reordered
* Bump sonic-platform-modules-arista
Improves i2c performance for xcvrs
Fix the led_plugin by ignoring unknown ports
Miscellaneous improvements
* Fix index column for Arista-7260CX3-D108C8
* Fix flash permissions for Arista platforms
The ext4 flash uses acl to properly handle permissions in EOS.
Aboot isn't built with this support and therefore can't be used
to set the flash permissions. It has to be deferred in sonic initrd.
moving to initramfs unifies disk allocate on different platforms.
use fallocate instead of dd to speed up the disk allocation.
By default, mkfs.ext4 has -E discard option which discards the blocks
at the mkfs time, also speed up the initialization time.
* Bump sonic-platform-modules-arista submodule
* Use sonic_sfputil plugin from the arista library
* Fix undefined variable varlog_size
* Prevent minigraph.xml to be removed from the flash
* Update DCS-7050QX-32 sensors config
On some platforms after the initramfs init scripts have mounted the root device its
block device disapear from /dev. The union-mount script therefore can't mount the
root device over the aufs. If this case happen, issue a rescan of the devices to
repopulate the /dev filesystem.
This commit will convert the existing file system of flash drive on Arista switches from VFAT to EXT4 in the booting of SONiC. It will take the whole flash and therefore remove the recovery partition. There is a check in the script making sure that the conversion operation will not happen on a non-Arista switch or if the existing file system is not VFAT.
