We are updating tlnet on a daily basis, but there is an archive for each
single day on my server. So you can get the installer that was in the
archive on a fixed YYYYMMDD.

In this case, you might call
	./install-tl --repository https://texlive.info/tlnet-archive/2021/01/28/tlnet/ --profile latex.profile
to ensure that the installer and the source of the installation comes
from the same day.

This way you can also ensure that the very same files are installed on
all servers.

No, that is not supported. But as said above, you can install an old
version.

It has, see above.

And the --repository works for both install-tl and tlmgr.

Thanks, took me lots of time.

Well, you can trick tlmgr to downgrade by
	tlmgr --repository /path/to/some/old/tlnet install --reinstall package
though I must say I have never tried that ...

Hope that clarifies a few things.
