Missing support for open_tree(2)

[sorenisanerd]

I'm attempting to run mkosi inside a sysbox powered container. It eventually fails because a call to open_tree(2) returns EPERM. It's a mount related syscall, so needs special attention.

Hi @sorenisanerd, thanks for trying Sysbox and filing the issue.

Yes Sysbox still lacks support for allowing the new mount syscalls (open_tree and friends) inside the rootless Sysbox container. This is definitely in the plans, but can't tell you to a timeline at this time.

Let's use this issue to track the action item.

Thanks.
