Conflict resolution (gtk, wayland)

2018-05-10 Thread Pierre Neidhardt

Sometimes when updating or install packages, guix encounters conflicts.
It's usually smart enough to fix it by itself.

That said, conflicts seems to be a telltale sign of bad packaging
(e.g. duplicate files in a package and its inputs).

Presently guix reports 3 conflicts on my install:

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

Let's lookup some referrers:

--8<---cut here---start->8---
> guix gc --referrers /gnu/store/mg1ilfq7ajcsk12kanzsbb8jhgv7g5vm-gtk+-3.22.29

/gnu/store/ki1c671fy8p1phvdlq9h6ff1nngynchj-profile
--8<---cut here---end--->8---

So if I get it right, gtk-icon-themes is an automatically generated
store items for each profile and it duplicates a file found in
gtk+-3.22.29.
Is this a packaging mistake?

Now to wayland:

--8<---cut here---start->8---
> guix gc -R /gnu/store/9hddxnv7q3q819axyw0yngzppmrgmjfi-mesa-17.3.8 | grep 
> wayland
/gnu/store/2w8lhl8hyvciy3hb0h2r0mbhx7pmniy1-wayland-1.15.0

> guix gc --referrers 
> /gnu/store/2w8lhl8hyvciy3hb0h2r0mbhx7pmniy1-wayland-1.15.0 | grep mesa
/gnu/store/9hddxnv7q3q819axyw0yngzppmrgmjfi-mesa-17.3.8
--8<---cut here---end--->8---

So mesa depends on wayland and wayland is properly referred to by mesa.
So far so good.  Same question: is this a packaging mistake?

Or, as a workaround, is it possible _not_ to install Wayland?

Re: encfs: fusermount: mount failed: Operation not permitted

By the way encfs is out-of-date: repo version is 1.9.1, but 1.9.5 is
out:

encfs: fusermount: mount failed: Operation not permitted

2018-05-10 Thread Pierre Neidhardt

I can't seem to be able to decrypt my encfs folders anymore:

--8<---cut here---start->8---
> encfs /foo /foo_mount
fusermount: mount failed: Operation not permitted
fuse failed.  Common problems:
 - fuse kernel module not installed (modprobe fuse)
 - invalid options -- see usage message
--8<---cut here---end--->8---

I'm quite sure it used to work on GuixSD, but I might be wrong.

Note that I use a custom kernel.  I've tried on Linux 4.14.33 and
4.16.6, same error.
