MF - Metadata file - A file inside the
repodata/and listed in therepomd.xml. -
OF - Other file - A file inside the
repodata/directory but NOT LISTED in therepomd.xml.
Regardless if used with or without --update createrepo output repodata/ looks like:
- All OFs stay there with unmodified content.
- Some MFs are regenerated. According to command line parameters at least the
primary.xml,filelists.xml,other.xml. MFs like groupfile (--groupfile) or databases (--database) could be regenerated as well if the options are used. - All MFs that were listed in the
repomd.xmland are not being regenerated, are kept in therepodata/directory but not referenced by the newrepomd.xmlanymore. (See: https://bugzilla.redhat.com/show_bug.cgi?id=950301#c1) - This behavior leads to the situation where old and outdated files like groupfiles or updateinfos are accumulating in the
repodata/directory over the time.
Regardless if used with or without --update, createrepo_c output repodata/ looks like:
- All OFs stay there with unmodified content, but each file is a copy so the file's metadata like mtime or number of hardlinks may be altered.
- All MFs are regenerated or removed.
- All MFs are regular files (not symlinks).
- All MFs have a number of hardlink references equal to 1.
