bash saved my day

less than 1 minute read

I was creating an ugly quick-and-dirty script to setup the squid cache_dir automatically with puppet based on the diskspace and memory available.

When you are developing you sometimes forget to create backups and push it to git, and mistakes are around the corner.

Lucky bash saved my day!

$ ./create_cache_entries.sh  > create_cache_entries.sh 
-bash: ./create_cache_entries.sh: /bin/bash: bad interpreter: Text file busy
$ vi create_cache_entries.sh

Ansible role: delegated_vm_install 1.1.0 released

4 minute read

playbook

I use KVM and cloud-init to provision virtual machines on my home network. I migrated all my services to Raspberry PIs running GNU/Linux and FreeBSD to save power.

I first wanted to use terraform, but the libvirt terraform provider wasn’t compatible with arm64 (at least at that time).

So I started to create a few ansible roles to provision the virtual machines.

delegated_vm_install is a wrapper around these roles to provission the virtual machine in a delegated way. It allows you to specify the Linux/libvirt KVM host as part of the virtual machine definition.

Changelog

delegated_vm_install 1.1.0

  • update_ssh_known_hosts directive added
    • update_ssh_known_hosts directive added to allow to update the ssh host key after the virtual machine is installed.
    • Documentation updated
    • Debug code added

Have fun!

OpenZFS

I use ArchLinux on my desktop workstation. For the root filesystem, I use btrfs with luks disk encryption and wrote a blog post about it.

https://stafwag.github.io/blog/blog/2016/08/30/arch-on-an-encrypted-btrfs-partition/.

My important data is on OpenZFS.

I’ll migrate my desktop to ArchLinux with OpenZFS in RAIDZ configuration as the root filesystem.

To make installation easier I decide to create a custom ArchLinux boot image with linux-lts and OpenZFS support.

You’ll find my journey to create the boot iso below. All action are execute on a ArchLinux host system (already using OpenZFS)
