As I was surprised to read
4. Vboxadditions is not working
I did a re-test with TC 2.11rc2 along the lines of what I did
here and have to report that all mounting attempts appeared to have
worked without an issue for me. Could it be that the required module was not loaded (with
sudo modprobe vboxvfs) as mentioned in the .info file?
I'm also not quite sure what is supposed to be wrong with 'midori': The installation works fine for me and the application is usable. The only (in my view entirely cosmetic) issue might be the fact that at the very first start a bit a garbled message might appear ("Error - %u The page '%u' couldn't be loaded. URL cannot be shown"). It appears that this happens when midori gets started via the wbar icon, and does not happen when started from the command line. A quick look into '/usr/local/tce.wbar' shows that indeed 'c: exec midori %u' appears to be the "culprit" here. I guess that OTOH might be a consequence of the 'Exec=midori %u' entry in '/usr/local/share/applications/midori.desktop'.
Likewise 'shiretoko' worked OK for my test. It's "just" fairly memory-hungry (ca. 23M downloaded extensions lead to ca. 50M extracted extensions). So running it on a system with only 128M would be pretty much pointless. But I fail to see what could be the issue re. TC 2.11rc2.
What I can confirm is the reported issue about applications not "showing up" via '~/.wmx/Applications'
I believe I've spotted one yet un-reported issue: the ownership of the files in '/home/tc/.wmx/SystemTools' is 'root:staff' even though a command in '/usr/bin/flwm_topside_initmenu' (i.e.
chown tc.staff -R /home/"$USER"/.wmx) tries to change this. I guess that command might have to be moved after the loop over the files in '/usr/share/applications/tinycore-*' to have the desired effect.
