this is a long shot, but i need help:

i’m creating a custom Win 11 24H2 image that included Sophos Endpoint Protection using sysprep/dism. sophos is being installed using the ‘--goldimage’ flag.

the image installs fine until after the first restart where it fails with “windows could not finish configuring the system” and gets stuck in a boot loop.

the same setup works without issues in 23H2.

#win11 #windows #admin #sysadmin #sophos

anyone have any ideas?? :boost_ok:

I've been struggling to understand why something was very slow on my Raspberry Pi.

I have a full blog post in the works about it, but I wanted to document how a simple tools like htop helped me rule out potential bottlenecks.

If you discovered other tools that made your admin life easier, please let me know!

Linux offers a variety of compression tools, each with its own performance characteristics

Below is a benchmark showcasing how some of these tools perform on a specific input file 😎👇

L’iMac pour bosser a un peu chaud, mais ça va ; je ne tire pas sur la carte vidéo. Pour la baie, je n’ai pas d’avertissements de vraie montée en température mais je surveille. La Freebox commence à chauffer (oui, son ventilo est mort mais j’en ai mis un externe). L’hyperviseur est ok. #sysadmin

It has been 0 days since I last had to reinstall my VCenter Server Appliance.

Since the broadcom acquisition, it sure is a pain to try and get updates etc configured correctly.

(Disclaimer: I'm not a pro VMWare admin, and I have pointedly ignored best practices. Like automated configuration backups.)

I'm still on track to move my lab to Proxmox, but that's gonna need some dedicated days to get running correctly.

Tonight I finally got round to a #sysadmin chore - migrating my home LAN's #UniFi controller from the venerable linuxserver.io Docker container (which was EOL in 2023) to a new #Debian VM running the UniFi deb packages directly.

It all went very smoothly; backed up the config from the old controller and restored it on the new. This means I get the latest version of the controller (something of a mixed bag; the new versions do try to upsell you on UniFi's cloud nonsense), and also the new VM responds to the hostname unifi which is required for provisioning some newer UniFi devices.

PSA: If you've lost your old ESXi perpetual key by updating to the latest version there is a workaround: Re-installing (not upgrade) the latest version 8.0U3e. Be sure to backup your VMs somewhere else!
