Proper permissions for /root directory?

What is the proper permissions for /root directory?
for Host and for containers?
I found out that default permissions in Ubuntu for both is 755
Are there any cons to set 700 for /root directory?
I cant find any guidelines about proper permissions for special directories in linux with systemd onboard.


You may find some information at the LSB,
When systemd supports private home directories, things might be different.

The /root directory by default is already 0700.

Not true
Ubuntu 20.04 LTS
defaults to 755 for /root
