Gentoo provides a package called app-admin/ansible for Ansible. To install it, just run: ❯ sudo emerge --ask app-admin/ansible Note that unlike Ansible package on CentOS/Fedora, there is no default ansible.cfg provided with the Gentoo Ansible package. ❯ ansible --version ansible 2.9.9 config file = None configured module search path = ['/home/kenno/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules'] ansible python module location = /usr/lib/python3.7/site-packages/ansible executable location = /usr/lib/python-exec/python3.7/ansible python version = 3.7.7 (default, May 9 2020, 19:52:18) [GCC 9....

I have a 2TB drive, when connecting to my Fedora workstation, it’s mounted using the UUID of the partition as the following: # mount | grep sde1 /dev/sde1 on /run/media/kenno/f59ffb93-5a92-4af9-a9b5-19ca3bb8aa37 type ext4 (rw,nosuid,nodev,relatime,seclabel,uhelper=udisks2) I think it’ll look nicer if it’s mounted with a shorter name, e.g. ‘Podcast’.

On most my systems I created a user called devops with its home directory created at /srv/devops. And on Fedora or CentOS systems, those home directories have their SELinux context set correctly when created.

I need to create 20 empty directores with the following name: dvd01, dvd02, dvd03,…, dvd20. My first thought was to use for loop, but then I decided to do a quick Google search, and found something more elegant: $ mkdir dvd{01..20} That’s cool, isn’t it?
