 ==== CentOS 8 Migration Notes ====

+When ssh'ing into a CentOS 8 machine via ssh and xterm, slow logouts usually occur. The fix is to not include ssh -X or ssh -Y.
+Consult [[virtualbox_for_centos_stream_notes|Virtual Box running CentOS8 Stream]] notes if dnf updates are slow
+Fix php for phpmyadmin:
+  dnf install php-gd php-ldap php-mysqlnd php-pecl-mcrypt php-pecl-zip
+Also comment out the cookie validity setting in config.inc.php
+Secure the mariadb
+Fix php.ini from known good config
+Configure $HOME/.vimrc as the following:
+  autocmd FileType * setlocal formatoptions-=c formatoptions-=r formatoptions-=o
+  # python3 -m pip install --upgrade pip
+  # python3 -m pip install dictor
+  # python3 -m pip install wheel
+  # python3 -m pip install httplib2
+  # python3 -m pip install PyMySQL
+PyMySQL v0.9.3 has been upgraded to v1.0.2 and requires modification to "connect" statement.
