dcb59c30d5 bash scripts: replace '[ ]' with '[[ ]]' for bash scripts
upstream: fedora

    bash scripts: replace '[ ]' with '[[ ]]' for bash scripts

    kdumpctl, mkdumprd, *-module-setup.sh only target bash, since they
    only run in first kernel and depend on dracut, and dracut depends
    on bash. So use '[[ ]]' to replace '[ ]'.

    This is a batch update done with following command:
    `sed -i -e 's/\(\s\)\[\s\([^]]*\)\s\]/\1\[\[\ \2 \]\]/g' kdumpctl, mkdumprd, *-module-setup.sh`
    and replaced [ ... -a ... ] with [[ ... ]] && [[ ... ]] manually.

    See https://tldp.org/LDP/abs/html/testconstructs.html for more details
    on '[[ ]]', it's more versatile, safer, and slightly faster than '[ ]'.

    This will also help shfmt to clean up the code in later commits.

8e51ebe6fb fadump: kdumpctl should check the modules used by the fadump initramfs
Resolves: bz1924115
Conflict: None
Upstream: Fedora

commit bf6671b60d
Author: Kairui Song <kasong@redhat.com>
Date:   Fri Jun 25 14:44:45 2021 +0800

    fadump: kdumpctl should check the modules used by the fadump initramfs

    After fadump embedded the fadump initramfs in the normal initramfs,
    kdumpctl will mistakenly rebuild the initramfs everytime.

    kdumpctl checks the hostonly-kernel-modules.txt file in initramfs
    to check if required drivers are included, but the normal initramfs
    is built in non-hostonly mode, so it doesn't have a
    hostonly-kernel-modules.txt file. The check will always fail.

    So let mkfadumprd make a copy of the hostonly-kernel-modules.txt in the
    fadump initramfs and let kdumpctl check that file instead.

96a3fc1ac8 fadump: isolate fadump initramfs image within the default one
Resolves: bz1924115
Conflict: None
Upstream: Fedora

commit fa9201b240 (devel)
Author: Hari Bathini <hbathini@linux.ibm.com>
Date:   Wed Jun 23 20:06:48 2021 +0530

    fadump: isolate fadump initramfs image within the default one

    In case of fadump, the initramfs image has to be built to boot into
    the production environment as well as to offload the active crash dump
    to the specified dump target (for boot after crash). As the same image
    would be used for both boot scenarios, it could not be built optimally
    while accommodating both cases.

    Use --include to include the initramfs image built for offloading
    active crash dump to the specified dump target. Also, introduce a new
    out-of-tree dracut module (99zz-fadumpinit) that installs a customized
    init program while moving the default /init to /init.dracut. This
    customized init program is leveraged to isolate fadump image within
    the default initramfs image by kicking off default boot process
    (exec /init.dracut) for regular boot scenario and activating fadump
    initramfs image, if the system is booting after a crash.

    If squash is available, ensure default initramfs image is also built
    with squash module to reduce memory consumption in capture kernel.
