[Message part 3 (text/plain, inline)]

There’s a bug with the ‘plan9port’ (p9p) package on Guix—installing it on the Guix System breaks Dired inside Emacs. When I try to open a Dired buffer with p9p installed, I get the following error:

> (error "Listing directory failed but ‘access-file’ worked")
> error("Listing directory failed but `access-file' worked")
> insert-directory("/home/guix/" "--dired -lFaGh1v --group-directories-first --time-..." nil t)

p9p distributes its own version of ‘ls’, so maybe that’s interfering?

The output of ‘ls’, on the command-line, with p9p installed is:

> ~% ls --version
> usage: ls [-dlmnpqrstuFQ] [file ...]
> ~% ls --help
> usage: ls [-dlmnpqrstuFQ] [file ...]
> ~% ls -v
> usage: ls [-dlmnpqrstuFQ] [file ...]
> ~% ls
> usage: ls [-dlmnpqrstuFQ] [file ...]

Which is odd and not how GNU ls is documented to behave. But executing ‘9 ls’, which is supposed to be the command to call the p9p version of ls, gives a different output (it lists my files and subdirectories as would be expected of ls) so it doesn’t appear that the ‘ls’ command changed to point to p9p’s ls.

Hello, I beileve this had been fixed with commit 2538a773c, which put
p9p into $out/plan9, only '9' is available via PATH.

User can append $GUIX_PROFILE/plan9/bin into $PATH if wanted.


Close now, thanks!
