< p > blendOS is self-described as "Arch Linux, made declarative,
immutable and atomic." And yeah, that's a pretty good
description of what it is. But you can never < em > really< / em >
tell what a distro is like without trying it, so...< / p >
< h2 id = "installation" > Installation< / h2 >
< p > I decided to just run blendOS in a virtual machine; I had a
bunch of data I hadn't backed up yet and was actively working
on, and didn't feeling like switching yet given I had no

experience with blendOS v4 - I've actually tried blendOS v3
2024-08-25 22:52:09 -05:00
before, back when v4 was in alpha, but it had practically zero
documentation, not even < code > man< / code > pages, so I gave up on
it very quickly. But with v4, hopefully it's improved since
then.< / p >

< p > Installation itself was simple: it's got a basic installer,
which notably allows for manual partitioning, but does
< em > not< / em > allow for selecting which track to use (which we'll
get to later), though to be fair, that's < em > very< / em > simple to
change post-installation.< / p >

< p > At first I wasn't sure what impl is doing, but according to
the < a

< p > This is actually a really interesting bit, as it means you
can just, say, host your own track(s) for all your computers in
a Git repo, and they can each inherit from other configs< a
href="#fn2" class="footnote-ref" id="fnref2"
role="doc-noteref">< sup > 2< / sup > < / a > or be overridden locally;
this actually seems like a very interesting and viable way to
centrally manage many computers running Linux, and given I'm
constantly switching between several computers; I can just put
my config(s) in one repo, and pull from that.< / p >

< p > < em > By far< / em > , the biggest of all blendOS's problems is how
slow it is to rebuild. It doesn't save "layers" like < a
href="https://coreos.github.io/rpm-ostree/">< code > rpm-ostree< / code > < / a >
(as used by Fedora atomic); instead, it just completely rebuilds
the system every single time. Because of this, it takes a long
time to run the updater/rebuilder, even to just install one more

< li > Its community and issue tracking is primarily on Discord,
which is then indexed by Answer Overflow so it's searchable with
Google and the like; there's no dedicated developer space (only
one issue on < a href = "https://git.blendos.co/blendOS" > their
GitLab< / a > , where < code > akshara< / code > is hosted.) However,
given you must be pretty competent with Linux to be using
blendOS in the first place, and how small the dev team and
community is, this isn't much of an issue.< / li >

docs are updated and getting new additions constantly.< / li >
