How to fix the rights of files and folders so that they do not change when digging from root?

Question

linux

If you dig into the folders of other users from the root, be it a regular user or www-data, then the rights to root are overwritten.

getfacl /home/vasya
getfacl: Removing leading '/' from absolute path names
# file: home/vasya
# owner: vasya
# group: share
user::rwx
user:vasya:rwx
group::r-x
mask::rwx
other::r-x

I tried to use acl:
setfacl -Rm u:vasya:rwx /home/vasya
But after creating directories from root, the rights to root are still assigned:

getfacl /home/vasya/test
getfacl: Removing leading '/' from absolute path names
# file: home/vasya/test
# owner: root
# group: root
user::rwx
group::r-x
other::r-x

How can one "fix" the rights of a directory so that they are also inherited by other directories?

Answer 1

setfacl -Rm d:u:vasya:rwx /home/vasya
setfacl -Rm u:vasya:rwx /home/vasya

Answer 2

Why bother with root?
Do su www-data or su and work with files.

Answer 3

In order to fix it, and not fix it after the change, you need to set setgid and setuid to the directory.
chmod -R u+s /home/vasya
chmod -R g+s /home/vasya

Answer 4

Theoretically, you can use chattr. But won't you create even bigger problems in this way? FreeBSD has a similar chflags command. So, after setting the system immutable flag (which makes any modification of the file impossible, root or not - fuck it) - it was possible to remove it only in single-user mode.
