Package: systemd Version: 247.3-6 Severity: normal Dear Maintainer,
Recently I renamed some *.link files on a headless server (changing the names inside the files to match), but after rebooting the server I was unable to access it. After much head-scratching I realized that the previous *.link files had been copied into the initramfs during a kernel package installation some time in the past, and the new files conflicted with the old ones, so systemd- networkd could not bring up the network interfaces. After searching the bug tracker I see that a number of people have been caught in this 'trap', and the advice given has been to run update-initramfs after making changes (or adding) *.link files. While that certainly does cure the problem, I can't find any documentation in the installed system which would have lead me to know that I needed to do that. Have I overlooked documentation of this behavior? It doesn't appear in systemd.link(5), and it doesn't appear in the 'networkd' section of README.Debian.gz for the systemd package. I can't be certain that this is Debian-specific behavior (an inquiry about that on the systemd-devel list hasn't elicited any responses), but it's definitely not 'upstream' behavior. Please consider documenting this in at least those two places in a very obvious way. I wish there was a more direct way to notify users that an initramfs update will be required, but short of having a daemon watch /etc/systemd/network for changes I can't think of any way to do that. I'd be happy to provide a patch to add this documentation to those two files if that would be welcome. Thanks for your time and consideration. -- Package-specific info: -- System Information: Debian Release: 11.2 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 5.10.0-11-amd64 (SMP w/8 CPU threads) 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 systemd depends on: ii adduser 3.118 ii libacl1 2.2.53-10 ii libapparmor1 2.13.6-10 ii libaudit1 1:3.0-2 ii libblkid1 2.36.1-8+deb11u1 ii libc6 2.31-13+deb11u2 ii libcap2 1:2.44-1 ii libcrypt1 1:4.4.18-4 ii libcryptsetup12 2:2.3.5-1 ii libgcrypt20 1.8.7-6 ii libgnutls30 3.7.1-5 ii libgpg-error0 1.38-2 ii libip4tc2 1.8.7-1 ii libkmod2 28-1 ii liblz4-1 1.9.3-2 ii liblzma5 5.2.5-2 ii libmount1 2.36.1-8+deb11u1 ii libpam0g 1.4.0-9+deb11u1 ii libseccomp2 2.5.1-1+deb11u1 ii libselinux1 3.1-3 ii libsystemd0 247.3-6 ii libzstd1 1.4.8+dfsg-2.1 ii mount 2.36.1-8+deb11u1 ii systemd-timesyncd [time-daemon] 247.3-6 ii util-linux 2.36.1-8+deb11u1 Versions of packages systemd recommends: ii dbus 1.12.20-2 Versions of packages systemd suggests: ii policykit-1 0.105-31+deb11u1 ii systemd-container 247.3-6 Versions of packages systemd is related to: pn dracut <none> ii initramfs-tools 0.140 pn libnss-systemd <none> ii libpam-systemd 247.3-6 ii udev 247.3-6 -- no debconf information
