 +====== Raspberry Pi ======
 +Model B+\\
 +OS: [[https://www.raspberrypi.com/software/operating-systems/|RaspberryPi OS]] until it was full of crap undebugable - then [[https://archlinuxarm.org/platforms/armv6/raspberry-pi| ArclinuxARM]] ... but ArchARM guys removed armhf architecture, very MS®© style (clap) so back to PiOS Lite\\
 +Installed with [[https://pi-hole.net/|Pi-Hole]] and unbound as [[https://docs.pi-hole.net/guides/dns/unbound/|recursive DNS on port 5335]]
 +Interface: http://192.168.1.10/admin pass in //bitwarden// \\
 +SSHKeys on root\\
 +
 +====== Archlinux ======
 +Start fdisk to partition the SD card:
 +<code bash>fdisk /dev/mmcb1k0 </code> thank you systemD for shit naming :!:
 +Delete old partitions and create a new one:\\
 +Type o. to clear out any partitions\\
 +Type p to list & check partitions. \\
 +Type n for new, p for primary, 1 for the first partition , press ENTER to accept the default first sector, type **+200M** for the last sector.\\
 +Type t for type, type c to set the first partition to type W95 FAT32 (LBA).\\
 +Type n for new, p for primary, 2 for the second partition on the drive, and then press ENTER twice to accept the default first and last sector.\\
 +Write the partition table and exit by typing w.\\
 +<code bash>
 +cd /root
 +mkfs.vfat /dev/mmcb1k0p1
 +mkdir boot
