Hi Everyone,
I have some old hardware that needs a refresh. The old machine is
running Fedora 40 x86_64 fully patched. The new machine is running the
same on a fresh OS install. I want to get a list of packages I
manually installed on the old machine, like Certbot, Emacs and Nginx,
so I can configure the new machine.
According to <https://discussion.fedoraproject.org/t/need-help-with-dnf-commands-for-listing-and-installing-packages-to-from-a-txt-file/74932>
and <https://unix.stackexchange.com/q/445003>, `dnf repoquery
--userinstalled` should list user installed packages.
However, I am seeing stuff I did not install. For example, on the new
machine, I only installed Zile (in place of Emacs due to Bug
#2316238). The other packages seem to be due system install or system
update.
[...]
I keep a ~/System directory where I note configuration changes I make to
the defaults and also a list of installed packages. I don't backup system files,
just my home directory and `/opt`. I do often end up with some installed
packages used only for testing/troubleshooting. The ~/System directory
allows me to rebuild a system after a disaster or configure a new machine
to my needs. It is not hard to determine which packages are missing in a
fresh install.
A list of installed packages right after a fresh install could be used to
generate a list of stuff added after the initial install, but if you end up
doing a fresh install on different hardware you might see some different
packages (graphics and network).
