Si cela vous est possible, pensez à mettre à jour vos instances. En effet, certaines mises à jour récentes, correctrices de bug, nécessitent que le réseau entier soit à jour... notamment concernant les doublons de messages entre instances.
Bien à vous et bonne lecture ! 📚 😜

Ok, I spent the last couple of days on this #brewfile project and figured it out with some help from my friend @BillWeiss

The #GitHub project I was initially pointed to for creating/ingesting brewfiles and trying to use has all sorts of issues, to the point where I ended up opening an issue with the project. The documentation is horrid, with all sorts of assumptions for the reader - it was painful. #KISS #keepItSimpleStupid

Thankfully BV pointed me to https://github.com/Homebrew/homebrew-bundle which just worked with no issues at all.

A simple
"brew bundle dump"
created the brewfile, added some edits and copied it over to my 'new' mac pro
then
"brew bundle install"
and things are getting installed!

If anyone has experience in ZFS errors, please help Collin! Unfortunately some errors have caused his instance birdbutt.com to go down and he could really use some assistance. If you know any ZFS wizards, they could be a huge help!

Unfortunately my experience level in ZFS is not as high as I wish it was.
