| Subject: init/main.c: add warning when file specified in rdinit is inaccessible |
| Date: Mon, 7 Jul 2025 09:14:11 +0000 |
| |
| Avoid silently ignoring the initramfs when the file specified in rdinit is |
| not usable. This prints an error that clearly explains the issue (file |
| was not found, vs initramfs was not found). |
