Description Paulo Andrade 2023-07-11 14:04:19 UTC 
Ownership of /dev/null is changed and cannot be changed.

  We believe this is related to:
https://github.com/opencontainers/runc/issues/3674
[permanent changes in ownership of /dev/null]

with patch
https://github.com/opencontainers/runc/pull/3707/commits/7e5e017dbab0f6ecb2c4b63c29c5ac44fc4e6ec6
[libcontainer: skip chown of /dev/null caused by fd redirection]

  Package installed is runc-1.1.4-1.module+el8.8.0+18060+3f21f2cc.x86_64
Comment 2 Giuseppe Scrivano 2023-07-24 10:24:21 UTC 
Kir, do we need to backport 7e5e017dbab0f6ecb2c4b63c29c5ac44fc4e6ec6 to 1.1.4?
Comment 3 Kir Kolyshkin 2023-07-25 00:27:00 UTC 
Yes; this was fixed in runc 1.1.5, here's the backport PR: https://github.com/opencontainers/runc/pull/3731

While at it, we can upgrade to the latest runc 1.1 (which now happens to be 1.1.8).
Comment 4 Giuseppe Scrivano 2023-07-25 06:48:59 UTC 
Thanks.

Tom, we will need to upgrade runc to 1.1.5.
