##Jentoo:
in /usr/src/linux kernelconfig  für Auswahl der Modules (danach auf save klicken)
dann kernel bauen in /usr/src/linux mit: make -j8 && make -j8 modules_install && make -j8 install && emerge -1 @module-rebuild
in /boot das neueste vmlinuz-...-gentoo nach EFI/Boot/bootx64.efi kopieren (mit y bestätigen, nicht enter!)
dann neu starten

PostgreSQL

## Temporally install the old version 
emerge -1  dev-db/postgresql:9.3
 
## Create database and config for the new version
emerge --config dev-db/postgresql:9.5
 
## Manually merge config
d /etc/postgresql-9.{3,5}/pg_hba.conf
#...
 
## Migrate
cd /tmp
sudo -u postgres -- pg_upgrade -d /var/lib/postgresql/9.3/data/ -D /var/lib/postgresql/9.5/data/ -b /usr/lib/postgresql-9.3/bin/ -B /usr/lib/postgresql-9.5/bin/
systemctl start postgresql-9.5.service
sudo -u postgres /var/lib/postgresql/analyze_new_cluster.sh
rm -R /etc/postgresql-9.3 /var/lib/postgresql/9.3

In some old instructions, steps can be found, which are not necessary anymore:

Copy config files from /etc/postgresql-*/ to /var/lib/postgresql/*/data/ (they are now symlinked)
Add local all all trust to /etc/postgresql-*/pg_hba.conf (it it there by default)

Arch Linux Version

systemctl stop postgresql
systemctl status postgresql

cd /var/lib/postgres
V=$(cat data/PG_VERSION)
mv data data-$V

install -d -o postgres -g postgres -m 700 /var/lib/postgres/{data,tmp}
cd tmp
sudo -u postgres -- initdb --locale en_US.UTF-8 --encoding=UTF8 -D ../data
sudo -u postgres -- pg_upgrade -b /opt/pgsql-$V/bin -B /usr/bin -d ../data-$V -D ../data
systemctl start postgresql
systemctl status postgresql
sudo -u postgres -- vacuumdb --all --analyze-in-stages

TeX Live manuell installieren

Zunächst als root

mkdir -p /opt/texlive /etc/portage/profile/package.provided
chown -R /opt/texlive # Den user hier angeben
cat >/etc/portage/profile/package.provided/notl <<EOF
app-text/texlive-2015
app-text/texlive-2016
app-text/texlive-2017
app-text/dvipng-1.15
EOF
emerge -cvaA `(echo virtual/latex-base ; EIX_LIMIT=0 eix -\# -I -C dev-tex)`
emerge -cvaA

… ggf. muss man noch Pakete die von texlive abhängen deinstallieren und nacher wieder installieren (doxygen, Anki, …) oder --nodeps verwenden

Dann als user ein TeX Live profile (in /tmp/texlive.profile) anlegen:

# It will NOT be updated and reflects only the
# installation profile at installation time.

For some Themes, the engine to be used is defined in gtk-2.0/gtkrc or gtk-3.0/gtk.css.

Some engines (like x11-themes/gtk-engines-xfce) have their themes included (no further package is required). Some themes depend on their engine (like x11-themes/light-themes depends on x11-themes/gtk-engines-murrine and x11-themes/gtk-engines-unico). You can use http://www.portagefilelist.de/site/query/file/?do#result to find Themes by looking for gtk.css.
