Yesterday I've upgraded F38-F49, all went fine, no issues. Today I tried 
F39-f40 and system freezes on autofs. Got some sssd errors, and i assume it 
might be all related (?).
There are no errors from autofs side itself, only warning:
"autofs.service: Referenced but unset environment variable evaluates to an 
empty string: OPTIONS"
. As soon as I enable autofs, all system is frozen (although my nfs mounts are 
set to 'soft').

I am getting those errors, which I have reported here 
(https://github.com/SSSD/sssd/issues/7314) as I saw something similar being 
reported year ago:
