''bootctl --path=/boot update''\\

/etc/mkinitcpio.conf:
MODULES="crc32_generic crc32-pclmul libcrc32c crc32c_generic crc32c-intel"\\

mkinitcpio -p linux


===== LXDE =====
''pacman -S lxde'' --> Standardeinstellungen, alle Pakete auswählen\\
''pacman -S xorg-xinit'' --> ~/.xinitrc erstellen, dort u.a. exec startlxde eintragen https://wiki.archlinux.org/index.php/Xinit

https://wiki.archlinux.org/index.php/Touchpad_Synaptics

==== Sound ====
''pacman -S alsa-utils''\\
alsamixer: unmute (m) speakers

==== Font configuration  ====

 ==== USB Automount  ====
udev-rule anlegen: http://kissmyarch.blogspot.de/2011/10/usb-automount.html\\
funktioniert nicht wirklich. udisks2 + manual mount does the trick. rw!!!

===== AUR (Arch User Repository)  =====
 ==== Installation von yaourt  ====
https://wiki.archlinux.de/title/yaourt\\
''pacman -S base-devel''\\
''pacman -S wget''\\
''pacman -S diffutils''\\

===== Nitrokey =====
https://www.nitrokey.com/documentation/installation#p:nitrokey-pro&os:linux\\
''pacman -S ccid''\\
laut Anleitung die libccid_info.plist anpassen (Nitrokey Kennungen eintragen)\\
udev-rule für den Nitrokey erstellen (evtl. beim Installieren der Nitrokey-App erledigt?)\\
udev neustarten? Keine Ahnung wie. Angeblich findet udev die neuen rules selbst...\\
''pacman -S snapd''\\
''systemctl enable --now snapd.socket''\\
''sudo snap install nitrokey-app''\\
rechner neustarten, dann kann nitrokey-app mit Fn+Alt+F2 gestartet werden, Nitrokey wird beim Reinstecken erkannt\\

btw: using subkeys... https://wiki.fsfe.org/TechDocs/CardHowtos/CardWithSubkeysUsingBackups\\

===== Gajim =====
OMEMO-Plugin braucht python-axolotl. Abhängigkeit python-axolotl-curve25519 muss aus irgendeinem Grund manuell installiert werden.\\
''yaourt -S python-axolotl-curve25519''\\
''yaourt -S python-axolotl''

===== Sonic Pi =====
''yaourt -S sonic-pi''\\
Installation von ruby-rugged schlägt fehl: falsche Version von libgit2 erwartet (0.25, installiert ist 0.26) (--use-system-libraries sollte aktuell installierte Version nehmen)\\
Das scheint ein Problem mit openssl1.1.0 zu sein. Empfehlung ist, alles mögliche mit openssl1.0 zu kompilieren. Funktioniert nicht wirklich besser. Gaaaa.\\

===== Google Chrome =====
https://linuxhint.com/install-google-chrome-on-arch-linux/\\
clone git repo\\
''mkpkg -s''\\
''sudo pacman -U google-chrome-xxx.tar.xz''

===== Docker =====
''sudo pacman -S docker''\\
''sudo systemctl enable docker.server'' (startet docker automatisch beim Hochfahren)\\
Neustarten, weil neues Kernelmodul bridge installiert wird...

''sudo docker pull couchbase/server'' lädt image herunter (latest version)\\
''sudo docker pull microsoft/mssql-server-linux:2017-latest''\\
https://docs.microsoft.com/en-us/sql/linux/quickstart-install-connect-docker\\

https://serverfault.com/questions/738773/docker-failed-to-add-the-pair-interfaces-operation-not-supported:\\
That is normal, since on a kernel upgrade, all .ko module files in /usr/lib/modules/{KERNEL_VERSION} of the running kernel are deleted. Docker needs some tun / tap modules to create the interfaces and trying to load them fails after a kernel upgrade. Rebooting helps because all module files are there for the new kernel. Another work-around would be to re-extract the modules for the old kernel if you still have the pacman package lying around and want to avoid the reboot. –


===== Email Backup =====
''sudo pacman -S offlineimap''\\
''openssl s_client -connect imap.provider.de:993 < /dev/null 2>/dev/null | openssl x509 -fingerprint -noout -in /dev/stdin''
