From 98aa4d5d242d3a73388271e00e11ce91d8c3c3e1 Mon Sep 17 00:00:00 2001 From: Lillian Berry Date: Mon, 7 Jul 2025 09:14:11 +0000 Subject: [PATCH] init/main.c: add warning when file specified in rdinit is inaccessible 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).
