Thanks for taking care of this problem, Salvatore!
AFAICT even latest busybox's sysctl does not support the `--pattern`
option yet:
| sysctl: unrecognized option '--pattern'
| BusyBox v1.35.0 (Debian 1:1.35.0-4) multi-call binary.
| [....]
So any initramfs that uses busybox and its sysctl (like in Debian)
and trying to apply above udev rules might fail?
