TODO: drop entry about renaming NamespaceId is inconsistent with our general spelling rules which say that capitalization of acronyms should not be changed when they are concatenated in CapitalizedCamelCase strings. But NamespaceId was added in f2ef8b28a5266a0070b0cb8b6375e418a5300975, before v249, so it's too late to change it. OTOH, NamespaceNSID cannot really be spelled in any other way. "NamespaceNsid" would be quite bad. So let's just ignore the inconsistency in naming, this seems to be the least bad option.
Rename uid0 to run0 Naming is always a matter of preference, and the old name would certainly work, but I think the new one has the following advantages: - A verb is better than a noun. - The name more similar to "the competition", i.e. 'sudo', 'pkexec', 'runas', 'doas', which generally include an action verb. - The connection between 'systemd-run' and 'run0' is more obvious. There has been no release yet with the old name, so we can rename without caring for backwards compatibility.
