There are some error messages when doing apply_binaries.sh on 36.4.4.
/var/lib/dpkg/tmp.ci/preinst: line 47: /proc/cmdline: No such file or directory
/usr/sbin/nv-update-initrd: line 92: /proc/cmdline: No such file or directory
checking to nv-update-initrd file , we thought it is not a good time to check /proc/cmdline file when apply_binaries.sh executed. because there is no /proc/cmdline file in rootfs/ at that monent.
