I compared this to the ext4 creation error. The code for __populate_fs
is more easy to follow. Basically this error means that st.st_mode
doesn't match S_IFCHR, S_IFBLK, S_IFREG and S_IFDIR checks.
I assume the files in home dir are created by useradd in some way that
bypasses pseudo. Then when tar / mkfs are executed, pseudo doesn't
know about the file and returns bad st_mode through lstat().
