[BUG] root user in the container does not have permissions to any files or folders

Is there an existing issue for this?

Current Behavior

I had this container running periodic backup and kept UpToDate with watchtower on the latest tag

but I noticed backup failing with permission denined. after investigation I noticed that the root user in the container does not have permissions to any files or folders. not just mounted folders that permissions can be messed up but to the container root directory.

I tested releases and found that this happened after the recent update from 1.4.5-r0-ls109 to 1.4.5-r0-ls110

This could be due to the rebase to alpine 3.20

Expected Behavior

on image tag 1.4.5-r0-ls109 and older
