set is parsing = from a string.
The -- is to stop the option argument parsing for safeness.
You can see the difference from the examples below.

Could you also filter the specific partition label, or other things indicating Arista prepared partition? I think the 'grep' is too loose here. #Closed

This is actually done in our script.
The check of Aboot=... kernel cmdline ensures that this is an Arista Switch. To differentiate Arista boxes from other platforms we use this parameter.
Here we obtain root=... from Aboot and it is stored as root_dev in this script, which is the root flash device. #Closed

Are these parameters good for any Arsita switches? What is the rule behind the numbers?

The script need a memory-based tmpfs to backup and restore the files in the flash during the conversion. The size of created tmpfs is expected to be as large as possible to backup all files in the flash, but it is constrained by the free memory available.
In the script, tmpfs_size is the size of tmpfs to create, and we expect that the free memory space is at least free_mem_thres, which is tmpfs_size + some extra.
According to our testing, the script with the current settings can always create a tmpfs, and never fail at the check of free memory space (line 123). (The script runs as the early stage of booting, so an extremely large portion of the memory should be free.) A special case is that when tmpfs_size is smaller than the total size of files in the flash (line 136), as there is not enough space to backup all files, the booting will continue without any change to the file system and partition. (But this will never happen on the boxes with 2G flash and 4G memory.)

This commit provides the following improvements to the Marvell armhf builds performed by Jenkins. 1. Improve build performance by attempting a build using SONIC_BUILD_JOBS=4. If that fails then try SONIC_BUILD_JOBS=2. If that fails then try SONIC_BUILD_JOBS=1. If that fails we are done. 2. Disable concurrent builds from the same branch. This strives to avoid a current armhf build limitation where multiple builds executed on the same build machine interfere with each other.

According to the system requirements software should never perform system thermal protection, since all the systems implement two levels of thermal protection: the first one is performed by firmware, the second, in case firmware was not able to perform protection, by hardware, while the temperature threshold for hardware protection is higher than for firmware. In both cases, when critical temperature is reached, system will be shutdown.

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.
