Package: udhcpd Version: 1:1.27.2-2 I noticed that the copy of /etc/udhcpd.conf installed by the udhcpd package includes a section describing the "remaining" option:
===== # If remaining is true (default), udhcpd will store the time # remaining for each lease in the udhcpd leases file. This is # for embedded systems that cannot keep time between reboots. # If you set remaining to no, the absolute time that the lease # expires at will be stored in the dhcpd.leases file. #remaining yes #default: yes ===== However, this option was actually removed from the udhcpd program many years ago, in commit 0416e3dde17ea9295635c52183b30fe3d7172333 (See, e.g.: https://git.busybox.net/busybox/commit?id=0416e3dde17ea9295635c52183b30fe3d7172333 or https://anonscm.debian.org/cgit/d-i/busybox.git/commit/?id=0416e3dde17ea9295635c52183b30fe3d7172333 ), and from the examples/udhcp/udhcpd.conf file in the upstream source in commit 2b0e95780863da44f6a9244699ece8620a599e19 . (Comparing those two files quickly I don't see any other obsolete option still listed in the Debian /etc/udhcpd.conf file.) Nathan
