执行update-initramfs -c -k 6.4.0-rt8发现生成的initrd非常大，有470M，以至于重启后显示：error: out of memory。我怎么解决这个问题？
我想删除一些由initrd提取的文件并重新压缩它们，但我不知道要删除哪些文件？
解压后的文件信息：
debian12@gyz:~/initrd/temp/test$ sudo unmkinitramfs initrd.img-6.4.0-rt8 .
debian12@gyz:~/initrd/temp/test$ ls
early main initrd.img-6.4.0-rt8
debian12@gyz:~/initrd/temp/test$ ls main/
bin conf etc init lib lib32 lib64 libx32 run sbin scripts usr var
debian12@gyz:~/initrd/temp/test$ ls early/
kernel
debian12@gyz:~/initrd/temp/test$
再压缩的方法是否正确？
find . | cpio -H newc -o > ../new_initrd
gzip -9 ../new_initrd
mv ../new_initrd.gz ../new_initrd
