I "managed" to install firebird3.0 and had a lot of trouble to find
where it chose to install itself. At last, I found it here

/snap/kde-frameworks-5-qt-5-15-core20/14/usr/share/firebird3.0-common

None of the hints given in various spots on the web led to a tool,
which could reveal this location or easily delete the package.

I also wonder about snap increasing its size on its own and needing
to be manually cropped down again.

Any hints?

Thanks, and regards,

I don't use any snaps, I just read things.

Just a general hint. I used (i.e. was forced to use) snap once, the installation hung during the snap process for hours, and after the
necessary interrupt/reboot left my system in an inconsistent faulty
state. It needed a complete re-install from scratch. It costs me a
lot time, some date, and nerves. Asking folks I was told to get rid
of it, completely. Searched and found some articles that I followed
(don't have the links but you'll find them yourself, I'm sure).

All the best.

Thanks for Your kind answer, Mike. I too don't use snap - it was
forced onto me and I HAVE TO use it. I did not search yet for
eventual benefits of it, and since I'm rather pleased with
ubuntu (18), and it is free, I do not feel very motivated to
criticise.

Yes, well, I'm new to Firebird, and since I did not find it in the
repository, I had to make do somehow. This is how I came
to firebird 4, and now wanted to get rid of the previous version,
which made me rendezvous with the snap.
The general idea of "list --all" is ok, but here the item ist buried
so deed in the structure that ist is very hard to discover. It is
tempting to just delete it, but then some other property might
feel disturbed.

Thanks, and regrads,

° Based upon Arch Linux;

° Curated rolling release — install once and simply keep it updated;

° Updates are bundled and always come with an announcement thread
at the forum (https://forum.manjaro.org) that addresses all of the
gotchas and how to deal with them;

° Three official editions (XFCE, Plasma and GNOME) and several
community editions (LXDE, LXQt, Deepin DE, Budgie, MATE, Cinnamon,
UKUI, OpenBox, i3, bspwm, et al), plus several "spins", created by
forum members;

° Uses Calamares as the installer, with support for btrfs and zfs;

° Comes with GNU bash as the shell for tty and system initialization,
as well as a themed zsh for terminal sessions within a GUI
environment;

° Supports multiple LTS kernels, as well as the latest mainline
kernel.

° Emphasis on usability rather than on politics, so proprietary
drivers are supplied without having to add special non-free
repositories;

° Supports the AUR ("Arch User Repository" [*]) via the Pamac GUI
package manager or via pacman wrappers such as yay or trizen. Pamac
can be used with a GUI or from the command line and offers optional
support for Snap and FlatPak. Supports AppImages too;

° Although not installed by default, ksh93 — which is the shell Janis
prefers — is available from the official repositories; and

° A great and very knowledgeable community to fall back upon.


[*] The AUR itself does not contain any software. It is a repository
with user-provided and human-readable and editable build scripts
(called PKGBUILD) that fetch the source code — or in some cases, a
binary — and build it into an ALPM-installable package on your own
computer. Some of those build scripts fetch pre-compiled packages
from the servers of other distributions — e.g. openSUSE or Debian —
and convert them into Arch/Manjaro packages, so that you wouldn't
have to waste hours on compiling the software, e.g. Google Chrome or
the nightly builds of Mozilla Firefox.

If you are going to use firebird 4, as far as I know the only available packages are snaps.

I don't know how to 'convert' a snap to a conventional .deb; I wish I
did. Everything I find wants to do it the other way around, converting
.deb/s to snap/s.

I'm asking because at some point (hardware incident, non-recoverable

further ZFS re-/installation activities; everything works smoothly.

Or are you just saying that ZFS is an option on a clean from scratch installation (where other distributions maybe don't support that FS)?

Snap(s) has a reputation. It seems that Ubuntu is pushing/marketing it hard
and it is upagainst AppImage and Flatpak. There is a following of Snaps are just the pits.

When I had snaps on the HD I was impressed at how many directories it
formed. Clutter and more clutter. Could not find anything amongst it.

So now my stance is now, No snaps if at all possible. To date I have been sucessful.

Why shouldn't it be not only possible but 'practical' for someone w/ a particular Ub distro v. to be able to build a conventional .deb package
from a snap package?

It must surely be 'easier' than compiling from source in terms of the methodology and 'risks' or possibilities of running into dependency
problem in a conventional compile from source.

Yes, it's the latter. For licensing reasons, zfs is usually not
supported in distribution installers, but Calamares does have support
for it now, with or without LUKS encryption. ;)

That said, personally I prefer btrfs, though. I don't have any
first-hand experience with zfs, but after many years of using XFS
(and reiserfs before that, and ext2 before that), btrfs suits my needs.
From what I've read, it either way does most if not all of the things
that zfs is supposedly popular for, and it's GPLv2-licensed. :)

I don't know btrfs, and, frankly, I use ZFS just because it had been
explained and recommended to me. The supported features are great as
I could see, but personally I use very little of all that. It's great
to know that (even in simple a 3-disk configuration) it continues to
work seamlessly even if one disk decides to disconnect or "give up"
(had that situation twice in the past years - no operation interrupt
was necessary, no data losses, or anything, did the disk replacement
and re-sync of disk-data without shutdown/reboot; a nice experience).

Yes, it's the latter.

And that is an issue, because using ZFS for root on, e.g., Debian is
somewhat involved <https://openzfs.github.io/openzfs-docs/Getting%20Started/Debian/Debian%20Buster%20Root%20on%20ZFS.html>
<https://noulin.net/blog/linux/2021/06/26/setting-up-root-on-zfs-in-debian-bullseye.html>. On Ubuntu it's just a click.

That said, personally I prefer btrfs, though. I don't have any
first-hand experience with zfs

I have used btrfs since IIRC 2013, and ZFS since ~2019. I have not
had problems with either within their supported functionality, but
last I looked btrfs did not properly support RAID 1, although it can
be made to if you are careful in the failure case <https://www.complang.tuwien.ac.at/anton/btrfs-raid1.html>; looking at <https://btrfs.wiki.kernel.org/index.php/Gotchas#raid1_volumes_only_mountable_once_RW_if_degraded>,
this is mentioned as a problem for kernels 4.9.x, 4.4.x, so maybe this
is fixed now.

Anyway, this problem with btrfs has led us to use ZFS on systems where
we want RAID1, and it has performed nicely; e.g., if we want to
install a new server with pretty much the same installation as an
existing one, we take one of the SSDs of the existing server, put it
and an empty SSD into the new server, put another empty SSD into the
existing server, type a few commands into both servers, change the
hostname, and presto, we now have two servers with RAID1.

Both btrfs and ZFS have their own set of management commands, so you
can reduce the mental load by only having using one of them, so in the
long run we will probably standardize on ZFS.

Yes, that has already long been fixed. RAID 0, 1 and 10 are fully
supported. RAID 5 and 6 on the other hand are experimental in btrfs and
should not be used on production systems.
