Originally intended to the Godson box on the Gentoo install a MiniDLNA, and then as a NAS to provide video source to the tablet, the result of hand cheap at the same time to update the world's operations. After the result is updated, the SSH connection prompts bash to be found.
Boot to another Debian system inside the box and find that the files themselves exist. Query Emerge.log, found that the final installation failed is Baselayout package, the error is said to Merge/lib32 directory.
A similar problem has been encountered before, want to view/bin/bash with LDD, but prompt "not a dynamic executable", directly execute prompt no such file or directory. Referring to this article, using readelf, read the bash file directly and find that it needs to use/lib32/ld.so.1, but the directory was killed by the Baselayout installation script. Manually create a soft connection, will/lib32->/lib, the system started OK.
