Now you have to create backing storage for extended attributes, ALC in
your case. This can be achieved by the following commands:
# cd /
# mkdir .attribute .attribute/system
# cd .attribute/system
# extattrctl initattr -p / 388 posix1e.acl_access
# extattrctl initattr -p / 388 posix1e.acl_default

After reboot you will have the ability to set acls on your root
filesystem. So issue the command:
# setfacl -m u:Jack: /boot

and check it with getfacl /boot. The output should be like:
...
user:Jack:---
...
