We encountered a file not found error when the symlink filesize is equal to 60: $ ls -l initrd lrwxrwxrwx 1 root root 60 Jan 6 16:37 initrd -> secure-core-image-initramfs-5.10.2-yoctodev-standard.cpio.gz When booting, we got the following error in the GRUB: error: file `/initrd' not found The root cause is that the size of diro->inode.symlink is equal to 60 and a symlink name has to be terminated with NUL there. So, if the symlink filesize is exactly 60 then it is also stored in a separate block rather than in the inode itself.
