lxqt-session permission issue

lxqt-session permission issue

[Reza Alizadeh Majd]

Hi Guix, 

It's a while I'm working on LXQt on Guix to improve and fix issues that 
might occur during it's usage. 

one of these issues is that when LXQt copies default openbox related 
configuration file (lxqt-rc.xml) it doesn't set proper permissions for it. 

I assumed that it might because of readonly nature of files inside store, 
for this I propose following patch for `lxqt-session` package: 

(add-after 'unpack 'patch-openbox-permission
           (lambda _
	     (substitute* "startlxqt.in"
               (("cp \"\\$LXQT_DEFAULT_OPENBOX_CONFIG\" \"\\$XDG_CONFIG_HOME/openbox\"") 
		(string-append 
			       "cp \"$LXQT_DEFAULT_OPENBOX_CONFIG\" \"$XDG_CONFIG_HOME/openbox\"\n"
		               "        # GUIX permission modification\n"
			       "        chmod -R 755 \"$XDG_CONFIG_HOME/openbox\"")))
	     #t))

now, I want to know if this could be an acceptable patch to submit to 
guix package repository or not ?

Thanks, 
Reza
