Can you please review and comment? Oh, yes, in fact this looks like a package-specific issue of the sort that I was just saying we didn't yet have any of to list at the end of issues.dbk, but would we want it there or somewhere else? It looks good, but of course as soon as I start thinking about how you'd add the markup I start reorganising... sendmail downtime during upgrade In contrast to normal upgrades of sendmail, during the upgrade of buster to bullseye the sendmail service will be stopped, causing more downtime than usual. For generic advice on reducing downtime see . -- JBR with qualifications in linguistics, experience as a Debian sysadmin, and probably no clue about this particular package

So, do you think this warrants a comment in the release notes? We already have a section about "prepare for downtime" [1], but if this went more smoothly in the past, it may me still smart.
