"grep: no such file or directory" during cpio step

[LIII-XXII]

Alright, this is maybe not a buildkernel issue, since it looks like it may happen in genkernel, but have you seen this before? I get this in the last steps of buildkernel.

31 Oct 2020: sadly, due to legal obligations arising from a recent change in my 'real world' job, I must announce I am standing down as maintainer of this project with immediate effect. For the meantime, I will leave the repo up (for historical interest, and it may be of use to others); however, I plan no further updates, nor will I be accepting / actioning further pull requests or bug reports from this point. Email requests for support will also have to be politely declined, so, please treat this as an effective EOL notice.

For further details, please see my post here.

With sincere apologies, sakaki ><
