I came to realise that suid is disabled by default in all my containers. While this makes sense from a security perspective, i need to have it enabled in one of them. Looking further I found this is set at storage level, with the mount options, so I figured there are 2 options:
a) re-mount that container it in its current storage (default) while omitting the “nosuid” mount parameter
b) create a separate storage dedicated to containers requiring suid, configure mount options without “nosuid” parameter, migrate the container from default storage
My questions: is option a) actually available? if not, is b) the correct approach ? If yes, how to change the mount options for the creation of new containers ? better, how to migrate a container between storage pools on the same host?
