SYNOPSIS         top

       lsinitrd [OPTION...] -k <kernel version>

DESCRIPTION         top

       omitted, then lsinitrd determines the default location based on
       the local configuration or Linux distribution policy.

OPTIONS         top

       -h, --help
           print a help message and exit.

       -s, --size
           sort the contents of the initramfs by size.

       -f, --file <filename>
           print the contents of <filename>.

       -k, --kver <kernel version>
           inspect the initramfs of <kernel version>.

       -m, --mod
           list dracut modules included of the initramfs image.

       --unpack
           unpack the initramfs to the current directory, instead of
           displaying the contents. If optional filenames are given, will
           only unpack specified files, else the whole image will be
           unpacked. Won’t unpack anything from early cpio part.

       --unpackearly
           unpack the early microcode initramfs to the current directory,
