Dear all!
I have Fedora Silverblue 33 and a fresh created toolbox (with sudo dnf update
), where I installed buildah.
But I haven’t got it to work. I tried with default /etc/sub{g,u}id
, which was empty, and also with the values from man podman
. It proceeds with warnings until buildah commit
, which fails.
On the host ( I masked my user by <USER>
):
$ cat /etc/subuid
<USER>:100000:65536
In the toolbox:
$ cat /proc/self/uid_map
0 1 1000
1000 0 1
1001 1001 64536
$ buildah version

The same WARN are with buildah from
and buildah run
.
But when committing, I faced following:

Do you have any useful link, hint, or idea how to solve it?
Thank you!
