prevent gc of texlive-...-texmf.tar.xz

[Thomas Danckaert]

Hi,

I have limited space on my root file system, and therefore need to 
run 'guix gc' regularly.  One problem with that is that the texlive 
source package (currently 
/gnu/store/mj40l554qxw15acz0h018gk5c9mxzfgn-texlive-20180414-texmf.tar.xz) 
regularly gets deleted that way.  When I upgrade after running guix 
gc, I often find I need to download this very large (2.5G) tarball 
again.


How do I add a gc root for this tarball (or is that a bad idea)?  I 
tried 'guix build texlive --source --root ...', but I get a warning 
'package texlive has no source'.


All ideas are welcome!

Thomas

I forgot to say I'm using the Guix System with this guix:

This one works fine for me; I get the same output as you.

In my case, I get the same output until the "doc-snarf" line (inclusive). The 
rest of the information is replaced by the output of a script I have in one of 
my project folders.

Could someone using the Guix System check if they can reproduce this problem, 
please?


Thanks for checking, Jérémy.

This problem still shows up in ‘guix system vm’, so it’s not related to

Alternately, what about adding ‘rottlog-service-type’ to

At the Guix Days we discussed using ‘add-temp-root’ and similar to
ensure that .drv files are at least GC-protected for the duration of the
session (connection to the daemon).

Does that address your problem?

Open MPI and its “drivers” (UCX, PSM, etc.) browse /sys, /proc, and /dev
to determine what devices are available.  Could it be that one of these
things is missing or different inside the container?  Does ‘strace’

Re: guix browsers timezones are set to GMT

Hi!

di...@santanas.co.za skribis:

> I see timezones in browsers on my guix system are set to GMT.

IceCat has a privacy feature turned on by default that, among other
things, has it not announce its timezone.

You can turn that option off by going to “about:config” in IceCat and
then turn off “privacy.trackingprotection.enabled”, IIRC.

However, that’s coarse-grain.  I’d love to have the option to just turn
off timezone concealing; anyone knows how to do it?

The ‘libtool’ executable provided by the ‘libtool’ package doesn’t
really matter.

Normally, Libtool is copied in package sources using ‘libtoolize’; only
when you run ./configure is a ‘libtool’ script generated for the program
you’re about to build.

The #:not-compiled-file-regexp option allows you to specify files not to
compile.  Let me know if it works for you.

Ah, that part is missing from the build system, we should probably add
it.  In the meantime, you can add a custom phase, as you wrote.

Yes, that did it! I could build and install my package successfully.

What does it mean "upgrade after running guix gc"?

If 'texlive' is installed in a profile, "guix gc" cannot delete it. Or
I miss a point.

Do you mean that you work only with temporary profile ("guix
environment") and you garbage collect each time you have ended with
this temporary profile and you create often the same temporary profile
(say '--ad-hoc texlive')? Is it what you mean?


However, note that 'texlive' could even be downloaded twice, I guess,

A quick workaround could be to create your own channel containing for
example this definition:

--8<---cut here---start->8---
(define-public my-texlive
  (package
(inherit texlive)
(version "mine")
(source (origin
  (method url-fetch)
  (uri "file:your/local/path/to/texlive-20180414-texmf.tar.xz")
  (sha256
   (base32
""))
--8<---cut here---end--->8---

So, you download once the texlive archive and you locate it somewhere
on your local disk. Then each time, you run "guix install
texlive@mine", Guix will compute the derivations etc. and will fetch
the source directly from your local disk.


It does not answer your question for protecting from GC but it should
avoid to download it again and again when you did a mistake with "guix
gc".



Hope that helps,
simon

how can I add a static IPv4 route?

Hello,

I have a very simple networking configuration:

--8<---cut here---start->8---
(service dhcp-client-service-type)
--8<---cut here---end--->8---

Please how can I add a static route? (I know there is wip-netlink, but
AFAIU it's still not in master)

I found a message from Julien [1] explaining he is using a custom
service [2] to define both IPv4 and IPv6 for the same device: do I have
to adapt that?

Since my guile-fu is very minimal, please do you have a snippet I can
reuse apart Julien's above?

Hi,

I only use this custom service because guix doesn't provide static networking 
for IPv6. However, if you don't need IPv6, I'd like to encourage you to use the 
static-networking-service that's described in the manual: 
https://guix.gnu.org/manual/devel/en/html_node/Networking-Services.html#Networking-Services

Otherwise, feel free to copy and adapt my stuff :)

The simplest way to make a gcroot is to symlink the store item into
/var/guix/gcroots.

In fact, I've had this exact symlink for a few years now:

lrwxrwxrwx 1 root root   73 Aug  5  2017 texlive-20170524-texmf.tar.xz -> 
/gnu/store/5rnvmy02yazy8iwaa91kijbbqp8qmflz-texlive-20170524-texmf.tar.xz

I think so, it at least seems to greatly reduce the chance the
derivations get removed. I made the Guix Data Service change here [1],
and I haven't seen the issue since.

Same thing here. It would be nice if we could somehow manipulate these

that work. Anyone has any idea if that is supported?
