Adding CDlinux to the CDlinux in the UD area causes the ISO or the two startup files (bzimage/initrd) to be put into the UD area to fail to guide the graphic interface, the solution is to package the extra part of CDlinux into initrd and view other online solutions such as Slitaz and Puppy. The process is simple: on the ext3 partition, unsquashfs (CDLINUX comes with) sequentially unpack base-cdl.md, basex-cdl.md, zh-cdl.cmd, spring-cdl.md, if there are other extension package, also unpack one by one and then step by step merge to the same directory, finally, package mksquashfs into an initrd.
