# RPM target
|
|
|
|
# ---------------------------------------------------------------------------
|
|
|
|
# The rpm target generates two rpm files:
|
|
|
|
# /usr/src/packages/SRPMS/kernel-2.6.7rc2-1.src.rpm
|
|
|
|
# /usr/src/packages/RPMS/i386/kernel-2.6.7rc2-1.<arch>.rpm
|
|
|
|
# The src.rpm files includes all source for the kernel being built
|
|
|
|
# The <arch>.rpm includes kernel configuration, modules etc.
|
|
|
|
#
|
|
|
|
# Process to create the rpm files
|
|
|
|
# a) clean the kernel
|
|
|
|
# b) Generate .spec file
|
|
|
|
# c) Build a tar ball, using symlink to make kernel version
|
|
|
|
# first entry in the path
|
|
|
|
# d) and pack the result to a tar.gz file
|
|
|
|
# e) generate the rpm files, based on kernel.spec
|
|
|
|
# - Use /. to avoid tar packing just the symlink

scripts/package: snap-pkg target
Following in footsteps of other targets like 'deb-pkg, 'rpm-pkg' and 'tar-pkg',
this patch adds a 'snap-pkg' target for the creation of a Linux kernel snap
package using the kbuild infrastructure.
A snap, in its general form, is a self contained, sandboxed, universal package
and it is intended to work across multiple distributions and/or devices. A snap
package is distributed as a single compressed squashfs filesystem.
A kernel snap is a snap package carrying the Linux kernel, kernel modules,
accessory files (DTBs, System.map, etc) and a manifesto file. The purpose of a
kernel snap is to carry the Linux kernel during the creation of a system image,
eg. Ubuntu Core, and its subsequent upgrades.

kbuild: add variables for compression tools
Allow user to use alternative implementations of compression tools,
such as pigz, pbzip2, pxz. For example, multi-threaded tools to
speed up the build:
$ make GZIP=pigz BZIP2=pbzip2
Variables _GZIP, _BZIP2, _LZOP are used internally because original env
vars are reserved by the tools. The use of GZIP in gzip tool is obsolete
since 2015. However, alternative implementations (e.g., pigz) still rely
on it. BZIP2, BZIP, LZOP vars are not obsolescent.
The credit goes to @grsecurity.
As a sidenote, for multi-threaded lzma, xz compression one can use:
$ export XZ_OPT="--threads=0"
