Title:
`sudo --login --user USERNAME` throws `setrlimit(RLIMIT_CORE):
Operation not permitted` error when run inside a container.
Status in sudo package in Ubuntu:
Confirmed
Bug description:
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:~$
