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
e42bcdcb
5cfc7ede

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.

The word "ALT" already contained in @relname@.
Added when call use/grub.

These changes allow you to create two independent config at the same
time or separately. It will be possible to add support for grub-pc in
the future.

The definition of the default menu item has been fixed.
Grub.cfg does not use label, uses --id.
It is assumed that --id is given last.

Not needed Stage1 package. They are added to mkimage.

The scripts were named the same for syslinux and grub. Because of this,
scripts for syslinux were overwritten by grub scripts.

NetworkManager not worked without udev-rule-generator-net on sysvinit

Many applications need a gnome-icon-theme.
