[Message part 1 (text/plain, inline)]

I have installed Guix with the script, and now cannot find the part of the documentation, that explains how to uninstall it.

Do you mean the guix-install.sh script? If so then what about the
https://guix.gnu.org/manual/devel/en/guix.html#index-uninstallation_002c-of-Guix
?

It says (a bit reformatted):

My 2 cents' worth:

That sounds dangerous -- what about putting all the deletions
in a TAR_DICT/TAR_FILE_NAME.tgz as a default, with suitable
default alternative commands for various capitalized names
in a (bash) select menu -- which could also include
    "Just do it, I know what --uninstall does")

Yeah a bit.

Eeeh? I don't understand what you mean.

Nevertheless, `./guix-install.sh --dry-run --uninstall` would be nice.
However the script is over 800 lines long. In bash! :-(
IMO before increasing script complexity with a new feature, we should
rewrite it to some reasonable language, preferably Guile Scheme. Or at
least Python.

Sorry, I should have explained.

I just wanted a simple way to save /exactly/ what uninstall would delete.
so it wouldn't be "irrevocable," in case the uninstall is too eager about its job ;)

A dry run of that size would be a scrolling blur, I think, and not much use unless
captured, and then it would take a lot of boring unreliable reading before you could
decide for sure that  it was ok to do the uninstall.

Maybe guix pack could make a tarball of exactly what uninstall would delete, e.g.,
	guix pack --uninstall-victim-files

with options of where to write it.

Well, guix pack is already scheme, right? Why couldn't it invoke uninstall after
safely having completed packing the uninstall-victim-files ?

WDYT? Simon? Ludo? Anyone? :)
