Hi, I would like to propose to plan to move to support merged-usr-only over the following releases. The motivation is bugs like [1] where upstream developers just use `/usr/bin/rm` (or other binaries, or user scripts using /usr/bin/bash, or ...) unconditionally; this was already a motivation to adopt merged-/usr as a default for me.
As far as I know nothing broke catastrophically over the last releases with merged-/usr. Alternatively, a team could form that preemptively looks at such issues and fixes them, ideally upstream. So a possible idea would be to: - For Debian 12 (bookworm): make it mandatory to migrate old systems to merged-/usr on upgrade. Possibly by allowing the existing usrmerge program to run from the initramfs. - For Debian 13 (trixie): packages should no longer install to /bin, /sbin, /lib, but to the respective locations under /usr.
