[artix-general] Wiki install page mistake

[Ruben Safir]

Like MBR, GPTs use logical block addressing (LBA) in place of the
historical cylinder-head-sector (CHS) addressing. The protective MBR is
stored at LBA 0, the GPT header is in LBA 1. The GPT header has a
pointer to the partition table (Partition Entry Array), which is
typically at LBA 2. Each entry on the partition table has a size of 128
bytes. The UEFI specification stipulates that a minimum of 16,384 bytes,
regardless of sector size, are allocated for the Partition Entry
Array.[5] Thus, on a disk with 512-byte sectors, at least 32 sectors are
used for the Partition Entry Array, and the first usable block is LBA 34
or higher. While on a 4,096-byte sectors disk, at least 4 sectors are
used for the Partition Entry Array, and the first usable block is LBA 6
or higher. 

That is just a quote from wikipedea... not my favorite source.

Eitherway, LBA 0 needs to be left OPEN

It sucks that this is so confusing now.  It sucks more that EFI /boot in
vfat doesn't work when that is supposed to be the new standard for UEFI
for the EFI boot location, rather than /efi/boot
