我玩过 Linux 自定义，当我想构建 .ISO 时，我收到此错误：
$ mkisofs -r -o rhel.iso -b isolinux/isolinux.bin -c isolinux/boot.cat ./
INFO: UTF-8 character encoding detected by locale settings.
Assuming UTF-8 encoded filenames on source filesystem,
use -input-charset to override.
Unknown file type (unallocated) ./.. - ignoring and continuing.
Using RELEA000.HTM;1 for /RELEASE-NOTES-pt_BR.html (RELEASE-NOTES-U1-pt_BR.html)
Size of boot image is 20 sectors -> mkisofs: Error - boot image './isolinux/isolinux.bin' has not an allowable size.
我没有更改isolinux.bin... 为什么我会收到上述错误信息？
