The root dir for filename is /var/lib/tftpboot
The first deployment you have to use the following command to populate the folder
[root@lnxks01 pub]# grub2-mknetdir -net-directory=/var/lib/tftpboot [root@lnxks01 tftpboot]# pwd /var/lib/tftpboot [root@lnxks01 tftpboot]# ls -lRt /var/lib/tftpboot/boot/ boot/: total 0 drwxr-xr-x 4 root root 59 Jan 22 2020 grub2 boot/grub2: total 16 -rw-r--r-- 1 root root 238 Oct 11 2019 grub.cfg drwxr-xr-x 2 root root 8192 Oct 7 2019 powerpc-ieee1275 drwxr-xr-x 2 root root 25 Oct 7 2019 fonts boot/grub2/powerpc-ieee1275: total 3520 -rw-r--r-- 1 root root 310788 Oct 7 2019 core.elf -rw-r--r-- 1 root root 26 Oct 7 2019 grub.cfg -rw-r--r-- 1 root root 2519 Oct 7 2019 command.lst -rw-r--r-- 1 root root 936 Oct 7 2019 crypto.lst -rw-r--r-- 1 root root 219 Oct 7 2019 fs.lst -rw-r--r-- 1 root root 3677 Oct 7 2019 moddep.lst -rw-r--r-- 1 root root 2568 Oct 7 2019 modinfo.sh -rw-r--r-- 1 root root 111 Oct 7 2019 partmap.lst ...

For a deployment using ftp
# yum install vsftpd
Open and edit the /etc/vsftpd/vsftpd.conf configuration file in a text editor.
Change the line anonymous_enable=NO to anonymous_enable=YES Change the line write_enable=YES to write_enable=NO.
Defaut folder for VSftp is /var/ftp/pub/
In this folder you 'll put the kickstart config file: ks.cfg
To bulid the kickstart file you can use examples or the kickstart generator https://access.redhat.com/labs/kickstartconfig/
