An mtree description of all non-zero files that make distribution installs (only size and md5) is built from the temproot. When the user completes a mergemaster run, the mtree description file gets installed into /var/db for safe-keeping. When the user then decides to do a subsequent upgrade (with the -U flag), the existing mtree description from /var/db is called into service looking for files that are different in DESTDIR. This is stashed away until a file that would normally end up prompting the user to look at changes is encountered. Since there are no user modified changes, the new file is installed without bothering the user. Looked at by: dougb MFC after: 6 weeks |
