Use ansible's inventory to ssh into hosts quickly, with bash completion! 
curl https://gist.githubusercontent.com/xenithorb/c50fd8b22b0d0a852d4f08b40c2fccf/ansible-ssh.sh  >> ~/.bashrc
. ~/.bashrc # Or open a new shell

Then, move to a directory with an inventory defined in ansible.cfg (most projects will have you define that per-project)

Basically, ansible-inventory --list needs to output vars when you're in your playbook directory for this to work

If it does you can now:

Add redundant menuentries in GRUB with extra cmdline paramaters
# IMPORTANT: Add the following to /etc/default/grub first!
#
# export GRUB_CMDLINE_LINUX_APPEND='<your_extra_cmdline_params>'
# export GRUB_OS_NAME_APPEND='<your_appended_id>'
#
# Note: ^ The export at the beginning is imperative unlike the rest
#
# Also maybe of interest (to save the selection):

A bash script to quickly unmount my layered external block device
#!/bin/bash
# A script to quickly unmount an external USB drive I have that I am using
# multiple block device layers with, like bcache, lvm, luks, etc.
# Assumptions here are that the aforementioned relevant crypttab and fstab
# entries are present. If they are, systemd should take care of the rest.
# If it works correctly, the last thing the mounting command should do is
# ask you for the unlocking password.
