Package: base-installer Severity: normal Tags: d-i Dear Maintainer,
When doing a network-install of a system, if one passes `hostname=foo` on the kernel commandline, the installer will use that to set the hostname of the installed system... EXCEPT if there's reverse-DNS for the IP address that we happen to have gotten from DHCP, in which case that takes precedence. But it shouldn't, we very explicitly are requesting a hostname to set. This situation happens in environments with dynamic dns where a client may have released an IP, the DHCP gave it out to this new client, but there's still a DNS cache with the old mapping. The installer should prefer the explicit preference set by the adminsitrator over the implicit one. Or, at the very least provide a configuration option to enable such a behavior. -- System Information: Debian Release: bullseye/sid APT prefers unstable APT policy: (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.10.0-3-amd64 (SMP w/12 CPU threads) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.utf8, LC_CTYPE=en_US.utf8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled
