It is included in the rootfs as /usr/bin/micropython.

Thanks, Rich!
It is bigger than Lua.

Depends on the features frozen into the main binary, and libraries included. Micropython is even getting asyncio support.
Since I use Micropython/Circuitpython on baremetal too, I choose to stay python.

after reading mention of micro python on this topic
i hapened to scrool past geophile/marcel:"A modern shell " @ https://github.com/geophile/marcel#scripting
--- Quote ---marcel provides a Python API, allowing Python to be used as the scripting language.
While Python is sometimes considered to already be a scripting language, it isn't really.
Executing shell commands from Python code is cumbersome.
You've got to use os.system, or subprocess.Popen, and write some additional code to do the integration.
Marcel provides a Python module, marcel.api, which brings shell commands into Python in a much cleaner way.
For example, to list file names and sizes in /home/jao:
--- End quote ---
--- Code: ---from marcel.api import *
for file, size in ls('/home/jao') | map(lambda f: (f, f.size)):
print(f'{file.name}: {size}')
--- End code ---
intresting

piCore has used micropython during the boot process for many years.
/usr/bin/tce-bootload is a micropython script called by tce-setup.
I think this was changed because, on the original Raspberry Pi's, this was the biggest bottleneck in the boot process.

Hi Greg Erskine,
Thanks for the information. piCore's /usr/bin/tce-bootload actively uses os.fork() and os.waitforpid(). Definitely micropython's os module gives better control over background processes than shell.
I don't write python, please correct me if I am wrong - os module is imported and it means that it is not compiled into the micropython binary, right?
