guix package: error: build failed: opening lock file?

[myglc2]

I am running a 'guix system vm' and 'guix package -i' fails ...

g1@server17 ~$ guix package -i icecat
guix package: error: build failed: opening lock file
`/gnu/store/4iznqdzql2cp4l2jkr09jn10xxw861c4-mirrors.lock': Read-only
file system

Any idea what I am doing wrong? Here are the details ...

guix system vm -M 4 -c 4 /home/g1/src/vm/vms/server17/server17.scm

sudo /gnu/store/1vnsn52grzvpzrdndv1f3nkf7mdwd5wk-run-vm.sh -name
server17 -net
tap,ifname=server17,script=/home/g1/src/vm/qemu-ifup,downscript=/home/g1/src/vm/qemu-ifdn
-daemonize -display none

TIA - George

Instantiating the OS declaration after a small change

[Arnaud B]

Hello everyone,

Context :
In the process of trying to build packages, through the use of guix
environments, I need more space on my home partition.
To do so, deleting former generations followed by 'guix gc' was not enough,
and I need to move things to my external ntfs drive (please don't ask why I
have to use that file system...).
As I'm regularly going to mount it, I added a file-system declaration in my
config.scm.

Question :
Do I have to apply 'guix system reconfigure', a lenghty process (on my
computer at least) for such a small change, especially if I did not write
it correctly, or is there another possibility ?  I actually just want to
test that file system declaration.
>From 6.2.13 of the manual, I'm thinking about 'guix system build'. Or could
I do it temporarily in another scm file ?

Many thanks in advance,

Arnaud

I am sorry for having taken this long to reply.  I (the original poster) was
thinking not of ‘master’ branch snapshots.  GNU Emacs has already branched the
upcoming Emacs 26, and the ‘master’ branch has been opened for the development
of what will be Emacs 27.  I was thinking of the latest official pretest version
of the almost-released branch (currently Emacs 26.0.91).  In my experience so
far, these pretest versions are reliable enough for daily usage.

Providing Emacs pretest versions would enable a larger audience to test them,
thus helping the GNU project.  It would also enable more people to
get Emacs from Guix; I need Emacs 26 for its better proxy support (so I can
install ELPA packages from my work desktop) and I really like its many other
features, so if Guix only has 25.3, I will continue to compile 26.0.9x manually
(and miss the Guix features).

I think it would be clearly beneficial to package 26.0.9x, unless Guix lacks the
manpower.  I unfortunately don't think I'll be able to help much, beyond testing
and filing bug reports.

OK, done.

As time passes, this test can no longer run given the constraints
above.  We should probably rethink it…

Yeah, well, no big deal.

Thanks,

This is exactly what I was looking for.  Thanks!

You can use ‘guix system extension-graph’ to view the graph of services
of your system:

  https://www.gnu.org/software/guix/manual/html_node/Invoking-guix-system.html

Alternately, you can inspect the ‘%desktop-services’ variable at the REPL:

--8<---cut here---start->8---
