The store listing carries the crate's MIT OR GPL-2.0-only expression, and both texts ride along in the snap under /usr/share/doc/pkh: the MIT grant requires the notice to accompany copies, and GPL-2 requires the license text with distribution.

summary: pkh is a packaging helper for Debian/Ubuntu packages
|
|
description: |
|
|
pkh aims at wrapping the different debian tools and workflows
|
|
into one tool, that would have the same interface for everything,
|
|
while being smarter at integrating all workflows.
|
|
|
|
This snap uses classic confinement and carries the packaging
|
|
toolchain it drives (dpkg-dev, git, mmdebstrap, lintian, quilt, ...)
|
|
so it behaves the same on any Debian/Ubuntu host.

# Host-side tools pkh execs directly. Tools that only run *inside*
|
|
# the build chroot (dose-builddebcheck, dpkg-cross) are provisioned

# there by pkh itself and must not be staged; likewise qemu-user-static

# is host binfmt configuration, not a bundled file.
|
|
#
|
|
# The apt and dpkg state-owning tools are deliberately excluded below:
|
|
# they must be the host's (classic mode makes them visible), since a
|
|
# core24 apt/dpkg managing a newer host's package database is exactly
|
|
# the version skew classic snaps must avoid. The source-package tools
|
|
# (dpkg-buildpackage, dpkg-source, ...) are bundled instead.
