Archlinux doesn't specify a value for this and relies on applications knowing
the default. Guix adds values to this list, meaning that because there is no
value initially it overrides the defaults completely. One thing that always goes
wrong when this happens is that Firefox installed through ‘pacman’ won't be able
to find some schemas it needs to show the upload file dialog and crashes when I
try.
The ‘syncthing-gtk’ program doesn't seem to start the syncthing daemon
automatically. In fact trying to start ‘syncthing-gtk’ through shepherd doesn't
seem to want to work at the moment, complaining that it can't close a bunch of
file descriptors.
The example was using a system constructor with a kill destructor, but I don't
think those two work together. I prefer having the application run in the
foreground and using the shepherd way of forking so I have more control.
I thought that ‘syncthing-gtk’ was a program that would fork (given the fact
that it has a ‘--quit’ command), but it turns out that it doesn't. Using the
system constructor means that shepherd will block until ‘syncthing-gtk’ is
closed.
Even though the output of the ‘--help’ command promises that ‘--file-guile’ is
the same as ‘-fg’ it appears that specifying ‘--file-guile’ doesn't work. It
just pops up the help message.
The herbstluftwm configuration isn't complete yet, it's only the package so far,
but it does extend the xsession service to include a line in xsession to execute
the window manager in a bit of a hacky way.
This also adds a ‘mixed-executable-file’ function which is the same as the
‘mixed-text-file’ except that it also sets the executable bit for the computed
file.
