Comment 0 for bug 1857036

When using `sudo --login --user USERNAME` with Ubuntu Focal currently, it will correctly operate but it will also throw the following error before continuing with the logon process:

sudo: setrlimit(RLIMIT_CORE): Operation not permitted

A full run of this was tested in a Focal LXD container after dropping to a root shell to reproduce (arstotzka is the host system, focal-test is the test container):

teward@arstotzka:~$ lxc shell focal-test
root@focal-test:~# sudo --login --user ubuntu
sudo: setrlimit(RLIMIT_CORE): Operation not permitted
To run a command as administrator (user "root"), use "sudo <command>".
See "man sudo_root" for details.

ubuntu@focal-test:~$

This appears to be similar to this issue identified on RedHat's tracker: https://bugzilla.redhat.com/show_bug.cgi?id=1773148
