Two failures from resumed kernel sessions: A resumed build re-runs debian/rules build, but the kernels keep their wrapper-step stamps in debian/stamps and the flavour config rule there exports .config from the annotations with no config prerequisite: the resumed build silently kept the previous attempt's configuration and a config edit never reached the .deb. Dropping the stamp cache unconditionally would impose the kernel packaging's shape on every package, so it is data-driven instead: packages declare the caches under a resume_clear quirk, and resumed builds remove those tree-relative paths before the build. The inner kbuild keeps its own incremental state, so only the cheap wrapper passes re-run and config-affected objects recompile. A SIGKILLed build (OOM) leaves its overlay mounts and /proc bind mount behind, and overlayfs creates root-owned work state inside the workdir: the next plain build (recording is always on, it replaces the session of its identity) failed to clear the leftovers with a permission error. Session clearing now unmounts everything under each entry at depth (re-reading /proc/mounts, tolerating mount stacks from consecutive crashes) and escalates through sudo; when the tree still cannot be cleared, the build reports it and continues without a session instead of layering over a half-cleared one.

# Quirks configuration for package-specific workarounds
|
|
# This file defines package-specific quirks that are applied during pull and deb operations
|
|
#
|
|
# `pull` and `deb` hold one entry per scope: several entries can carry
|
|
# different `series` lists, and every matching entry applies in file
|
|
# order. Entries can be scoped with `series`: an empty list applies to
|
|
# every series, otherwise only the listed ones. Packaging workarounds
|
|
# should carry the series they were verified against so they can be
|
|
# dropped once the upstream packaging catches up.
|
|
|
|
quirks:
|
|
|
|
# The resolute kernels declare `llvm-21-dev` unqualified while their
|
|
# other llvm pieces are `:native`; the dpkg cross rules then resolve it
|
|
# against the host architecture, whose dependency closure conflicts with
|
|
# the `:native` python3. Resolve it against the build architecture
|
|
# until the control is fixed upstream.
|
|
# The resolute and stonking kernels declare the host-tool libraries
|
|
# unqualified (libelf-dev for resolve_btfids, libdw-dev for
|
|
# gendwarfksyms, libssl-dev for sign-file), unlike the Debian control,
|
|
# which carries the same names qualified `:native`. The dpkg cross
|
|
# rules resolve an unqualified Multi-Arch: same name against the host
|
|
# architecture only, so a cross build installs no build-architecture
|
|
# variants and the kernel's host-side tools cannot link. Inject the
|
|
# build-architecture variants until the control is fixed upstream.
|
|
# The kernel's debian/rules keeps its wrapper-step stamps in
|
|
# debian/stamps, and the flavour config rule there exports .config from
|
|
# the annotations with no config prerequisite — a resumed build would
|
|
# keep the previous attempt's configuration and silently ignore config
|
|
# edits. List the stamp cache under `resume_clear` so resumed builds
|
|
# drop it and re-run the wrapper steps; the inner kbuild keeps its own
|
|
# incremental state, so only the cheap wrapper passes re-run. This is
|
|
# the packaging's long-standing shape rather than a fixable regression,
|
|
# so the entry applies to every series.
