Why does anaconda not enabling dump and fsck fields for filesytems mentioned in /etc/fstab in installed Red Hat Enterprise Linux 7?

Issue

• In Red Hat Enterprise Linux 6.x, anaconda was enabling the dump and fsck fields for filesystems in /etc/fstab file as follows.

[root@localhost ~]# egrep -v "^$|^#" /etc/fstab
/dev/mapper/myvg-rootvol /                       ext4    defaults        1 1
UUID=21756916-4a76-4492-b962-ba533f7ebb89 /boot                   ext3    defaults        1 2
/dev/mapper/myvg-homevol /home                   ext4    defaults        1 2

• Whereas in Red Hat Enterprise Linux 7.x, it doesn't and looks like follows.

[root@newrhel7 ~]# egrep -v "^$|^#" /etc/fstab
/dev/mapper/rhel_newrhel7-root /                       xfs     defaults        0 0
UUID=97ad9c1d-0311-49c8-9d3c-d0b832b061e6 /boot                   xfs     defaults        0 0
/dev/mapper/rhel_newrhel7-swap swap                    swap    defaults        0 0
