### User story Running the MergeUploads task takes longer than expected for an (apparently) simple combination of 2 .changes files. ### Error handling This is due to relying on `mergechanges`, a script which comes from `devscripts`, a large set of Debian tools with has a lot of dependencies; and installing+running it inside a full container (through unshare). ### Implementation plan We could reimplement it directly in Python: https://salsa.debian.org/freexian-team/debusine/-/merge_requests/1117#note_527761 and also moving this to a ServerTask (without Worker).
