Currently, the following packages are listed individually in the "System
tools" section: s6, s6-linux-init, s6-linux-utils, s6-portable-utils,

The packages s6, s6-linux-init, s6-rc are the ones to use for building a
real s6-based init system. s6-linux-utils and s6-portable-utils provide
alternatives to busybox/coreutils and a few niceties (e.g.
s6-fillurandompool). They can be used with any init systems.

It looks sensible to move them to a submenu named "s6 system management"
and add mdevd to it to avoid confusion. But IMHO other skarnet packages
like the execline scripting language should be kept out of it as it not
s6-related, though used most of the time when building a s6-based init
