This is an interesting case. Small containers, systems and chroots that need an init really want to use sysvinit (thus initscripts) instead of systemd, as it's drastically smaller, both in terms of memory use and disk size. Thus, they're what needs removal of e2fsprogs the most -- ie, adding the dependency wouldn't be the right thing to do. > initscripts was identified as potentially needing such a dependency, > because it mentions tool names from e2fsprogs in the following files: > > /etc/init.d/checkfs.sh contains logsave.

If I read codesearch's output right, there are only two packages that use it: * initramfs-tools * initscripts /sbin/logsave is currently linked against libblkid.so.1 and libuuid.so.1 -- but, that's wrong: it doesn't use any symbol from either. This currently wouldn't save us anything as other executables in e2fsprogs have a valid reason for this dependency -- but not logsave itself. It also doesn't need any other piece of e2fsprogs. The autoconfage is purely historic as <signal.h> is mandated by POSIX (thus present everywhere) while <getopt.h> and its #else stanza are redundant with <unistd.h> (POSIX mandates short getopt() since times immemorial). Thus, logsave is a single self-contained .c file that can be tossed around and shipped in any arch:any package. One possibility is initscripts itself -- while it currently doesn't have anything but pure ASCII shell scripts, it's arch:any as its contents differs on non-Linux, and is too low-level for runtime detection to be reasonable. I don't know if initramfs-tools uses logsave on systemd machines, though. As you have researched relationship between minimal install packages, you likely know more than me. Thus, could you advise?
