Thank you for finding out that "adduser me boinc" fixes this! But why
this problem doesn't exist before? Some recent permission changes on
/var/lib/boinc-client/slots/?

This solution (requiring a user to be in the boinc group) is not so
problematic. It's just similar to the cdrom/floppy/... groups, where
debian-installer adds the first (non-root) user to those groups, and
other group management task is up to the system admin.

Two concerns here:
- Security? when a user is in the boinc group, he/she is considered as
  an admin for the boinc daemon, and should be able to do whatever
  he/she wants with boinc. Thus no problem here.

- UI? Instead of crashing badly, there should be an error message about
  not being in the boinc group. (I don't know if upstream supports
  this.)

Cheers,
Yixuan
