user-password based encryption of the home directory, so the password is required to unlock it (no admin access)
That seems like a very niche feature given that it is only relevant if the admin isn’t the same person as the user but the admin would have to set it up and condemn themselves to hearing endless whining from users who lose their files when they forgot their password.
SElinux is a “global ACL.” You can stop root from doing anything you like with it. Usually by accident and without realizing it’s been done in my experience…
No, that is just not true. You can stop root from doing things without a reboot with SELinux but encrypting something with a password root does not know actually does stop them from doing it at all short of a brute force attack on the encryption.
Oh, I was specifically thinking that admins that have users either competent enough not to forget/lose their passwords or mature enough not to whine to the admin when that causes the loss of all their files are pretty niche.
I don’t know, unless I personally allow the admin to have that kinda access to my files I wouldn’t really want it. And for that case you can enroll recovery keys (which would need to be manually stored, but still) or a fido token or whatever other supported mechanism there is, its LUKS2 backed encryption after all. Then there is also the possibility to just not encrypt the home directory at all.

Let me introduce you to selinux.
In what way does selinux allow your users to lock themselves out of their own home directories in a way that the admin can not fix?

That’s true - you can often recover a bad ACL. I was thinking more of the “niche use case” where separating duties and restricting root are concerned.
