Package: dropbear-initramfs Version: 2016.74-5+deb9u1 the dropbear initramfs-tools init-premount script does include the config file of the post-initramfs dropbear.
This is likely not desired because when you run dropbear in initramfs you will usually use a different config (like different port). Of course there are different options to work around this, e.g. /etc/initramfs-tools/initramfs.conf, but in my opinion dropbear-initramfs should use its own config from /etc/dropbear-initramfs/ instead of relying on the system one from /etc/dropbear/. # dpkg -S /usr/share/initramfs-tools/scripts/init-premount/dropbear dropbear-initramfs: /usr/share/initramfs-tools/scripts/init-premount/dropbear # dpkg -l dropbear-initramfs Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Architecture Description +++-============================================================-===================================-===================================-============================================================================================================================== ii dropbear-initramfs 2016.74-5+deb9u1 all lightweight SSH2 server and client - initramfs integration # cat /etc/debian_version; uname -a 9.6 Linux debian 4.9.0-8-marvell #1 Debian 4.9.130-2 (2018-10-27) armv5tel GNU/Linux *** dropbear 2018-08-24 02:08:38.000000000 +0200 --- dropbear.fixed 2018-12-31 15:17:05.569984908 +0100 *************** *** 38,44 **** DROPBEAR_OPTIONS="$PKGOPTION_dropbear_OPTION" fi if [ -e /etc/dropbear/config ]; then ! . /etc/dropbear/config fi . /scripts/functions --- 38,44 ---- DROPBEAR_OPTIONS="$PKGOPTION_dropbear_OPTION" fi if [ -e /etc/dropbear/config ]; then ! . /etc/dropbear-initramfs/config fi . /scripts/functions
