pkgbase vs bectl?

D

djfiander

The old freebsd-update system (which I'm still using on almost all my systems) created a new boot environment when it installed a patch, but pkg doesn't. I understand why; it's not like pkg knows that this "pkg upgrade" is upgrading base, necessarily, but it might be nice to add an option to pkg to create a boot environment during pkg installation/upgrade.

Also, the errata notices give information for performing a binary system update using freebsd-update, but don't provide instructions for doing so with pkgbase.

Release 15 is something in between, pkgbase is supported, but not recommanded by the installer if I am not mistaken, it is "tech preview", so it says it all, if you want it then take it as it is(that's how I see it).
Give the devs some time to add all the features freebsd-update already have, release 16 might be better in this regard.

Personally I use my personal script for any upgrade, it creates a BE mount it then performs the upgrade in it. So far so good, I am not a professional, so careful it might not be bullet proof.
 
gotnull, that's correct, it's marked as Tech Preview. It was still marked that last time I tried FBSD-16-CURRENT snapshot, so I don't know if it will change by the time 16 comes out. (Snapshot is from 2026-01-13, if anyone cares).

This is a reasonable idea, but since "I" never know, creating a new BE would almost need to be the default; either I add the option or the option defaults to "true".
One could do magic with pkg upgrade -n | grep pkg base stuff to help decide "yep need to create a BE", but is that more work than just always create a new BE?
Always creating a new BE means you need to periodically do "bectl list" and "bectl destroy -o" to keep BEs managable (like snapshots, BE reproduce at the same rate as rabbits, nominally 5 litters per year after about 6 months, 3 to 4 babies per litter)
If one follows quarterly, perhaps managable, but one could miss out of band security updates.

I personally don't know the "right thing" to do, just we (the community) needs more documentation, comparing pkgbase to freebsd-update and really thinking about edge cases.

gotnull thanks for sharing script.
 
In Solaris 11.4 pkg decides whether or not to create a New Boot environment when a Patch or a monthly service repository upgrade is processed.


I believe that FreeBSD should also do that. The trigger for this New Boot environment should be provided in the PATCH !

as an example:

In a future upgrade from FreeBSD 16-Release to Freebsd 16-P1 a flag in the "Patch Header" should trigger a new Boot environment if Boot filesystem is ZFS.

Doing this may rescue a lot of installations in the event of an issue.

Hi
Your script is very useful in my pkgbase zfs environment.
I've always used:
alias up 'pkg upg -n'
But this is cleaner:
alias upsafe '/root/bin/upsafe'
upsafe` (is your script.)
Thanks

I believe that pkgbase should be official when 16.0-RELEASE will be out, devs have 2 years to work on it, it surely will be in better shape than what it it now, will see :)

You're welcome ;)
I took a lot from the community (wise advice, good how-to, nice writings) for years so if I can share something useful from time to time, I do it.

Glad it helps ;)
I agree the name is probably not easy to write for daily use.
I picked that name mainly because it is easy to remember what it does just by looking at its name, I do that now because after few months/years I usually forget why I called a script like this and what it does, so now I avoid troubles by picking a long and boring name ^^


drsnx60 nice, It sounds like a great idea for our FreeBSD devs.
 
pkg(8) seemingly has a 'plugin' infrastructure. Doesn't seem to be used at the moment, also couldn't find much documentation about it. But I suspect it might be possible to write a plugin that automatically creates a bectl(8) snapshot (similar to what freebsd-update(8) does) with every pkg upgrade run.

Code: 
dice@armitage:~ % pkg plugins -l
NAME       DESC                                          VERSION
dice@armitage:~ %

There's only a cursory mention in pkg(8), and there's no pkg-plugins(8). So I haven't quite figured out how you could use it.
 
I believe at some point freebsd-update is meant to be re-implemented to make use of pkgbase and as such would carry the boot environment functionality along with it. (hopefully I didn't imagine reading that but it's been a few months:)

There is one plugin ports-mgmt/pkg-provides, I've already used it in the past but honestly I totally forgot that it was a so called "plugin".
This is the message displayed by pkg during its installation:

Code: 
~ > pkg info --pkg-message pkg-provides
pkg-provides-0.7.4:
On install:
In order to use the pkg-provides plugin you need to enable plugins in pkg.
To do this, uncomment the following lines in /usr/local/etc/pkg.conf file
and add pkg-provides to the supported plugin list:

PKG_PLUGINS_DIR = "/usr/local/lib/pkg/";
PKG_ENABLE_PLUGINS = true;
PLUGINS [ provides ];

After that run `pkg plugins' to see the plugins handled by pkg.

On upgrade:
To update the provides database run `pkg provides -u`.

So I did what the message says and it works.
Code: 
~ > pkg plugins    
NAME       DESC                                          VERSION   
provides   A plugin for querying which package provides a particular file 0.7.4

The package installs a binary written in C I believe:
Code: 
~ > file /usr/local/lib/pkg/provides.so
/usr/local/lib/pkg/provides.so: ELF 64-bit LSB shared object, x86-64, version 1 (FreeBSD), dynamically linked, for FreeBSD 15.0 (1500068), stripped

At this point I am not sure shell scripts can work as plugins, C is probably more efficient for pkg, skilled coder will be needed for that, not me ^^
Also I failed to find other plugins other than pkg-provides, which makes me wonder if plugins are still a thing? I think odd not being able to find documentation about it except manpage pkg.conf() which is pretty light.

Yes, the handbook, last I looked, seemed a bit behind. I have a page on it, covering a few things that I didn't find at the time, much of it based upon posts here (and some reddit ones) at https://srobb.net/fbsd14_15.html, including using bectl to give you a fallback.
