I use pcmanfm in openbox and the only difference is that mountable volumes through the fm vanished.
I guess the gvfs process provide thunar with this ability (mounting and umounting volumes and drives, permanent and temp) and pcmanfm uses
that ability but does not have it on its own.  So in order to have this thunar must also be installed, or it came along back with gvfs.

Gui crap!  Now I understand what virtual file system means.

In the barricades (a las barricadas) with a hood on and only the eyes looking at you, with a rock in the other hand, she will be there.

gvfs is not in there.

I've burried one long ago and I am nursing the second one hopefully for longer than I can.  But early on I did all the things they wouldn't let me.
I still try.  Look for squats, protests, little bookstores, and non-pop live music.  There are the only safe havens for people who can trully love and are
capable of.  The rest you can buy and sell at the bazar.

Old and cranky works best, they can ruin men just as well.

I may be too new to help you, and I started with a clean install side by side to a debian install.
Get a list of your needed software, copy your home into the same name and user id in the fresh
installation, and run them and compare for yourself.
I have pulled and stretched this thing in all ways, it is not braking yet.  I jumped from jessie
(boring) to ascii (equally boring) and now to ceres.  The only problem I experienced was with
the availability of my browser that will not upgrade in ceres, but the same problem exists in sid.

I don't think I am going back, other than from quriocity to see how things are evolving in
contrast with devuan.  I am so happy with it I can feel what people feel getting out of "jail".

I remember seeing in the devuan page a document of trying it your way.

PS  Wait until you try the refractasnapshot to backup your system and create a live
iso out of your system as well.  It is 4 clicks away.  It was science and research in debian
to do the same.  And I never wanted to do a dissertation in live image production.
This is like cheating on Debian with her sexier funnier twin sister!

It will not install in sid either

Debian is just as democratic as any western democracy.  It is organized so the public is excluded from the
decision process.  Participation and representation by demagogues and populists is an insult to the ideal of democracy.

You, the OP, are judging future as a dynamic process having a static picture.  Your premise is that debian due to
the high current number of developers will continue developing a good solid system.  This is a "if ... " loop you are
trapped under.  "If" Debian took the wrong turn a while back due to a bad "political decision" influenced by
market and not solid scientific reasoning, Debian will run aground in uncharted waters.  So If and "if not else" is
very significant in analyzing your question.  Look up here and elsewhere postgres and uncontrollable logging
and tell me why so many developers not only can not fix will not even accept this is a bug causing problems
to servers (as a user I can't tell this is a problem).  19log entries a minute without the possibility to stop them
is a problem for any server that does not just deletes all logs in equal rates.

In any way you look at it, it is a bet.  I am betting due to the political decision and philosophy of Devuan.
I have been twice in life abandoned a love relationship, still in love, because of problems of cohabitation.
This is how I feel about debian.  I loved it and still wish I could live with it, but I'd rather not.  I think Manjaro
with OpenRC was a rebound relationship, I'd like to make a family with Devuan now.

Live long and prosper my friends.

The only reference in this forum of Qupzilla is yours, now there will be two.
It is not as minimal in footprint as portrayed, but in Devuan it is alot lighter than in systemd distros.  Somehow all the qtwebkit processes that would run along in systemd (10-15 of them) are not active here.  But I am confortable with it and it is not made by google/mozilla Inc.  Midori was crap, I only struggled with it for a couple of days.  Dillo is fine if you are editing plain no script html pages and want something light to visualize them in the background.  For plain html5 pages/sites (devuan/debian/torproject/etc) it may be fine.

Qupzilla 1.8.* is more than 2 years old.  Sid/Ceres is now testing 2.1.2 ....  WHAT A LEAP!  Manjaro has had 2.1... in stable for quite a while.  As I write this I am upgrading to ceres from ascii as it is the only way I can get qupzilla.  Sounds silly, I know.  I have my refractasnapshot done (you guys should try it if you haven't already).
Guess what!  If you use qupzilla from jessie/ascii to reach qupzilla's website to download and build their latest the javascript link to download for "other linux" does not work.  Their own site does not work with an older qupzilla to download the newer one!

That is why I like it so much    It is like buying a Trabant or a Yugo when nobody wants even the one they have.  I wanted to make a 2stroke clone of the two and call it Zastrabant

Tell me you used google to translate an old mariners' term into nonsensical english! 

I have been meaning to send that email for translational availability but I am still in the other end of the tunnel, playing nurse for some genetically related person.  It has been a long haul.  Being unable to stick to a seat for more than 10' does not help with writing much in any language.  I'd rather upgrade a pentium 1 from wheezy to sid than write a whole paragraph.

If there were 2 or 3 of us keeping the pressure among ourselves to do it, it could be significant.
