Antranig VartanianFreeBSD-Update and ~200 JailsInitially, when I heard about <code><a href="https://rustdate.over-yonder.net/" rel="nofollow noopener" target="_blank">freebsd-rustdate</a></code> I was very skeptical. I have a fear of “Written in <new hip language>”. I thought, however, I’ll wait, and when the time comes, I will try and see how it works.For the last couple of days I’ve been updating hosts and jails for my customers and my company, and one of the best resources I found was the <a href="https://wiki.freebsd.org/FreeBSD_Update" rel="nofollow noopener" target="_blank">FreeBSD Update</a> page on FreeBSD’s Wiki, specially the “<a href="https://wiki.freebsd.org/FreeBSD_Update#freebsd-update_Reverse_Proxy_Cache" rel="nofollow noopener" target="_blank">freebsd-update Reverse Proxy Cache</a>” section. It has saved me hours when updating the hosts. For some hosts we even did an NFS mount of <code>/var/db/freebsd-update/files</code> directory.But when it came to upgrading the jails, I realized that this is going to take a very long time. Each host has at least 15 jails, up to 50. There’s a host which has 100+ jails.Upgrading all of them was going to take a very, very long time. So I ended up doing some research. Here were my options.<ul><li>Build FreeBSD once and run make install everywhere else using NFS and DESTDIR (I used to do this years ago)</li><li>Migrate to PkgBase (we’ve started doing this, but we’re not done yet, and it will take a while)</li><li>Nuke the Jails, start fresh, and just move the data (this could work, and I will do that in the future, but now I need to update ~200 jails in the coming 3 days)</li><li>Somehow, make <code>freebsd-update</code> run faster.</li></ul>As you have guessed, I went for the last option. Uncle <a href="https://people.freebsd.org/~dch/" rel="nofollow noopener" target="_blank">Dave</a> reminded me of <code>freebsd-rustdate</code> again, and I decided to give it a try. Even before starting, my good friend <a href="https://belltower.it/" rel="nofollow noopener" target="_blank">Daniel</a> wrote in our group chat:<blockquote>@dch my guy. You just saved me several hours per year of flipping back and forth between terminals waiting for the next part of a freebsd-update upgrades to finish running on a million systems.</blockquote>I arrived to my parent’s house, installed <code>freebsd-rustdate</code> on a host, and tested it on a single jail. Here is my initial reaction<blockquote>holy fuck freebsd-rustdate is fucking fast</blockquote>Like I said, I hate “rewrite in <new hip language>”, but clearly, this time it’s a winner.And frankly speaking, my Jail manager, <a href="https://jailer.dev/" rel="nofollow noopener" target="_blank"><code>jailer</code></a>, does have the same problems that <code>freebsd-update</code> has. It’s much, much slower when you have to manage 100+ jails. I will, however, not rewrite it in another language (for now, and if I do, it will be in Oberon). Although I might end up spending some good amount of time optimizing it 🙂Kudos to <a href="https://www.over-yonder.net/~fullermd/" rel="nofollow noopener" target="_blank">Matthew Fuller</a>, amazing work. And I have to mention, when I was thinking about moving to FreeBSD more than a decade ago, his rant “<a href="https://www.over-yonder.net/~fullermd/rants/bsd4linux/01" rel="nofollow noopener" target="_blank">BSD for Linux Users</a>” was the deciding factor for me, and I’ve been using FreeBSD ever since.That’s all folks…Reply via email.<a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://antranigv.am/tags/freebsd/" target="_blank">#FreeBSD</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://antranigv.am/tags/jailer/" target="_blank">#Jailer</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://antranigv.am/tags/matthew-fuller/" target="_blank">#MatthewFuller</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://antranigv.am/tags/oberon/" target="_blank">#Oberon</a> <a rel="nofollow noopener" class="hashtag u-tag u-category" href="https://antranigv.am/tags/rust/" target="_blank">#Rust</a>
