Apology for upside-down title. I cannot pinpoint where problem is.
While fiddling many system settings (!!), my Penguin was mostly healthy but somewhat went wrong.
Situation
Thunar volume management got unstable. (probably) I cannot reproduce.
What I did
I did many things, shape up kernel, shape up installed packages, and system upgrade.
I remember that fuse package choked while system upgrade. (I did not pay much attention. I simply removed it. I also removed many packages which did not look essential. (This caused trouble later, I guess)
Troubleshooting process
For some reason, udisks package was gone. (udisk2 stays) I simply tried to reinstall udisks, and ran into something like
this or
that.
I tried several things, install makedev, check if chroot exists... None of them worked.
Bingo(??)
I turned off fuse kernel opt for unknown reason. After turning it back on, fuse is happy. (even without makedev)
a long way to go
I guess I am still underway to achieve final goal. There may be some other unknown problems also...
If anybody else run into same situation, check these points. I appreciate further explanation.
cheers
