[ubuntu/jammy-proposed] initramfs-tools 0.140ubuntu12 (Accepted)

initramfs-tools (0.140ubuntu12) jammy; urgency=medium

  * Force copy pthread and libgcc_s libraries via a stub binary.

    To avoid circular shared library dependencies between compiler and
    libc, libpthreads chooses to dlopen libgcc_s, instead of linking
    against it. However, we have no way to parse/know what it
    needs. And even when we hardcode to include libgcc_s1, we don't
    have a way to know which libgcc_s1 is needed on a given system and
    from which path to include it. But there is a hook-function to
    copy a binary and all of its shared library dependencies. Thus
    create a stub empty executable, with shared linking against
    pthreads and gcc_s1 and always include it in the initrd. This way
    at initrd creation time, ldd is used to correctly resolve these
    shared library dependencies and correctly copy them into the
    initrd. This removes hardcoding paths as to where these libraries
    must be copied from on the host. LP: #1958594 LP: #1880853

  * For net boot include most of net/usb modules, except niche modems. LP:
    #1950996

  * Cherry-pick updated merge request !26 to support xz compressed
    firmware. Uncompressed firmware is preffered, with a fallback to use
    compressed firmware files. LP: #1942260

  * Cherry-pick updated merge request !51 to decompress compressed kernel
    modules for boot speed performance. LP: #1932329
