[gentoo-user] EINVAL

[gentoo-user] EINVAL

Hello,

I am successfully updating a remote system using ssh and screen, but for some packages (e.g. rust, thunderbird, firefox) during the pre-merge checks I get this message:

Unable to unshare: EINVAL (for FEATURES="ipc-sandbox network-sandbox pid-sandbox")

FEATURES in my make.conf contains 'parallel-fetch -userfetch nodoc -xattr'; the update is run as root; kernel is 5.5.3-gentoo.
I never noticed it for local updates, is it related to the remote operation? Should I take some action?

Thanks,

raffaele

Is the CONFIG_UTS_NS kernel option enabled?

No, I don't have that option set in the remote machine's kernel and changing the kernel right now is not an option, so I'll have to live with it.
In the local machines running kernel 5.6 the option is set but I don't remember setting It myself, so I suppose it is done by default as stated in one of the replies to the fist link.

Thanks,
