Install new package in current generation?

Install new package in current generation?

[Jone]

Now:

guix package -i PACKAGE  # -> creating new generation
guix package -d          # remove all generations, except current
guix gc

- not so good: first creating new generation, and next delete all
others (I absolutely do not need a rollback).

Maybe some other way?

There is no other way.  Guix always generates a new generation of your
profile.

Technically you don't need to always call `guix gc`.

Also note that generations are generally lightweight, especially for
simple operations like installing a single package.

It's right. But I have another problem with different generations:
I build and install xfce4-cpugraph-plugin

/gnu/store/qf0khvz9vj5lj4k9sfjxqlbs0kl8ssr3-xfce4-cpugraph-plugin-1.0.5/

│           └── plugins
│               ├── libcpugraph.la
│               └── libcpugraph.so
...

of course xfce-panel does not see libcpugraph.so

Problem! Probably I should to modify the "xfce" package itself, but it's
not so easy for me.

Garbage collection won’t make a difference here.

According to the definition of the “xfce” and “xfce4-panel” packages,
plugins are searched for on directories listed in the environment
variable “X_XFCE4_LIB_DIRS”.  Try setting that to the directory
containing “xfce4-cpugraph-plugin” before Xfce is started.

It works! Thanks.

Indeed, just run it when you need more disk space.  On some machines I
have “guix gc -F100G” run periodically, which ensures that 100G of disk
is available.
