Use systemd-settings-enable-log-to-tty12 (included by +systemd-optimal)
instead.

Module efivars will be loaded by udev now.

+systemd-optimal do not call +systemd more.
Also added +systemd-optimal into jeos-systemd, regular-server. Need
to disable core dump

rootfs is not required to be installed on lvm2.

Kernel module snd-seq-midi is not compiled for mcom02.

This is necessary to prevent accidental hit of another branding.
Usually the problem is solved by setting up pkgpriorities  in apt settings.
But this is inconvenient when you need to make building often with others
branding.

Users expect that if virtualization is selected during installation
of the distribution, the libvirtd service will be enabled.

VM_INITRDFEATURES qemu not allowed for e2k only. This feature
added modules optionaly.
VM_INITRDFEATURES usb allowed for all arches, but the presence of all
modules is required. Therefore, for all arches all usb modules are
optionally added.

The entry in /etc/fstab about the mount parameters of the root
partition needs to be done not only for builds with u-boot.
But, if the record already exists, then it will not be added.
The file system type is set by the variable VM_FSTYPE.

Since packet sorting is enabled by default, then
the order in KFLAVORS has ceased to matter.
Kernels are always installed in alphabetical order.
Therefore, it makes no sense to sort by buildtime.

Also fixed my typo. When creating a symlink, the variable
$kver was used, i.e. the entire list of kernels, not the
last value $KVER of the list.

tar2fs does not run in hasher and without qemu. This causes build
problems for an architecture other than the host.

If build is performed on a system with EFI Secure Boot enabled,
then grub will not boot even on EFI without Secure Boot.
This problem is caused by the use of the --removable option, which
is not compatible with option --uefi-secure-boot  the current grub.
Option --uefi-secure-boot is enabled automatically if the system is
booted in EFI Secure Boot mode.

Added for EFI only (see stage1/scripts.d/01-grub).

Also:
- added new target jeos-systemd,
- disabled quiet for cmdline kernel
- returned to its original form regular-jeos-ovz

Do not create syslinux.cfg if EFI_BOOTLOADER is set to not equal grub-efi.

These are partial commits reverts:
01ee4075

This is necessary to prevent unintentional assignment of rEFInd
as EFI_BOOTLOADER.
I also want to hope that memtest86.efi can be made to work from
grub-efi in the future.
