System Configuration

Generate fstab:

mkdir -p /mnt/etc/
for i in ${DISK}; do
   echo UUID=$(blkid -s UUID -o value ${i}-part1) /boot/efis/${i##*/}-part1 vfat \
   umask=0022,fmask=0022,dmask=0022 0 1 >> /mnt/etc/fstab
done
echo $(echo $DISK | cut -f1 -d\ )-part1 /boot/efi vfat \
   noauto,umask=0022,fmask=0022,dmask=0022 0 1 >> /mnt/etc/fstab

Configure dracut:

echo 'add_dracutmodules+=" zfs "' > /mnt/etc/dracut.conf.d/zfs.conf

Force load mpt3sas module if used:

if grep mpt3sas /proc/modules; then
  echo 'forced_drivers+=" mpt3sas "'  >> /mnt/etc/dracut.conf.d/zfs.conf
fi

Set locale, keymap, timezone, hostname and root password:

rm -f /mnt/etc/localtime
systemd-firstboot --root=/mnt --prompt --root-password=PASSWORD --force

Generate host id:
```
zgenhostid -f -o /mnt/etc/hostid
```

Install locale package, example for English locale:

dnf --installroot=/mnt install -y glibc-minimal-langpack glibc-langpack-en

Enable ZFS services:

systemctl enable zfs-import-scan.service zfs-mount zfs-import.target zfs-zed zfs.target --root=/mnt

By default SSH server is enabled, allowing root login by password, disable SSH server:
```
systemctl disable sshd --root=/mnt
systemctl enable firewalld --root=/mnt
```

Chroot:

m='/dev /proc /sys'
for i in $m; do mount --rbind $i /mnt/$i; done

history -w /mnt/home/sys-install-pre-chroot.txt
chroot /mnt /usr/bin/env DISK="$DISK" bash --login

For SELinux, relabel filesystem on reboot:
```
fixfiles -F onboot
```
Set root password, the password set earlier does not work due to SELinux:
```
passwd
```
