Hi,
I ran "guix home import". The output seems mostly reasonable, but the use
of 'local-file' seems troublesome:
;; [comments]
(use-modules [modules])
(home-environment
(packages [stuff])
(services
(list (service
home-bash-service-type
(home-bash-configuration
(bashrc
(list (slurp-file-gexp
(local-file "/home/[USER]/.bashrc"))))
(bash-profile
(list (slurp-file-gexp
(local-file "/home/[USER]/.bash_profile")))))))))
IIUC, when I will run "guix home reconfigure", guix home will intern
~/.bashrc and ~/.bash_profile in the store, build things, and eventually
replace ~/.bashrc with some symlink to something in the store.
I assume this technically all works out, but this seems a bit irreproducible.
What I made modifications to ~/.bash_profile? It seems like, if I run "guix home reconfigure"
on the same system, the modifications will be preserved, which is fine. However,
what if I log into another system, copy the home configuration, and run "guix home reconfigure"
from there? Then "guix home reconfigure" would pick up the ~/.bash_profile from the new system
(without the modifications) instead of the old system, right?
Then the home configuration generated by "guix home import" isn't self-contained,
which seems unfortunate.
Two proposals for addressing the issue:
(1) Use 'plain-file' instead of 'local-file', to include the contents of ~/.bashrc inside
the generated configuration
(2) Let "guix home import" create a directory with the "home-environment.scm", ".bashrc"
and ".bash_profile".
Greetings,
Maxime
