persistent drive mappings to host tree

[Zugschlus]

Hi,

I am using bottles 63.2 in flatpak on Debian Linux. In bottles, I have installed a commercial app that I use to write invoices. The invoices are on the host filesystem in /home/myuser/path/to/some/dir. I add a mapping to that directory in bottles > mybottle > settings > Manage Drives, select H, click the √, select the drive letter, click on the file symbol, browse to my path and click OK.

In result, the bottles dialog shows a mapping from the drive letter to /run/user//doc/[[:xdigit:]]/dirname and I can work with that drive, until I log out of my Linux session. When I have logged in again, I have to repeat the motions I outlined above. The drive mapping is still visible but not valid any more. I have to delete and start over.

What am I doing wrong?

Greetings
Marc
