Re: Udev Rule Not Triggered

Antwane,

Great that you got it to work!  There are some landmines left that I'd 
like to point out so they don't bite you later (what? they're 
mixed-metaphor cartoon landmines!):

Yes, but *your* use of it isn't. :-)  You didn't add any newlines so 
everything ends up on one line, which can't work [well].

This URL is bogus?  It probably works for {you,now} because Guix is 
content-addressed and you've previously downloaded a file with that hash 
to your store.  If it ever gets garbage collected, Guix will be unable 
to download again.

I advise against using an external file for such a trivial rule at all, 
and simply fixing the string-append until it works (and the actual file 
contents look correct).

Kind regards,

T G-R
