Package: dropbear-initramfs Version: 2025.89-1 Severity: normal X-Debbugs-Cc: [email protected]
Dear Maintainer, I am reporting an issue where the backgrounded network configuration loop in `dropbear-initramfs` survives the transition to the real root filesystem (switch_root), causing infinite console spam and resource leakage. **Description of the script logic:** In `/scripts/init-premount/dropbear`, the script backgrounds the `run_dropbear` function for local mounts: ```sh run_dropbear & echo $! >/run/dropbear.pid ``` The `run_dropbear` function calls `configure_networking`. When no `ip=` parameter is provided via the kernel command line, `configure_networking` (from `/scripts/functions`) enters a long-running or infinite loop waiting for network initialization. **The Issue:** While the script saves the PID to `/run/dropbear.pid`, the cleanup mechanism intended to run at `init-bottom` appears to fail or is bypassed when the rootfs is a ZFS dataset or when the pivot occurs under specific conditions in Debian Forky/Sid. The console is spammed with: `dropbear: line 151: cat: not found` `dropbear: line 340: sleep: not found` **Steps to Reproduce:** 1. Use a ZFS root filesystem with native encryption. 2. Do not provide an `ip=` argument in the bootloader. 3. Unlock the ZFS pool via the physical/serial console. 4. After the OS boots, observe the persistent "not found" errors on the console. **System Information:** Debian Release: forky/sid Architecture: arm64 Kernel: 6.19.10+deb14-arm64 -- System Information: Debian Release: forky/sid APT prefers testing APT policy: (500, 'testing') Architecture: arm64 (aarch64) Kernel: Linux 6.19.10+deb14-arm64 (SMP w/8 CPU threads; PREEMPT) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages dropbear-initramfs depends on: ii busybox-static [busybox] 1:1.37.0-10.1 ii dropbear-bin 2025.89-1 ii initramfs-tools 0.150 ii udev 260.1-1 Versions of packages dropbear-initramfs recommends: pn cryptsetup-initramfs <none> dropbear-initramfs suggests no packages. -- no debconf information
