I'm trying to set up a server using PXE and following this (clickable) instruction. But I have a problem in part Creating your NFS installation Right here: Copy kernel and initrd to tftp root. Run these commands ON THE SERVER sudo cp ~/vmlinuz-`uname -r` /tftpboot/ sudo cp ~/initrd.img-`uname -r` /tftpboot/ Actually, I don't know which kernel (server's or client's) should be copied. There isn't any files like those in my home folder on server. Can anybody tell me how to fix it?
