Relocate RPM/DNF databases to /usr
Summary
Currently, the RPM and DNF databases are located in /var. Let's move them to /usr.
Owner
- Name: Chris Murphy
- Email: chrismurphy@fedoraproject.org
Current status
- Targeted release: Fedora Linux 36
- Last updated: 2021-12-06
- FESCo issue: <will be assigned by the Wrangler>
- Tracker bug: <will be assigned by the Wrangler>
- Release notes tracker: <will be assigned by the Wrangler>
Detailed Description
Current location
/var/lib/rpm /var/lib/dnf
New location
/usr/lib/sysimage/rpm /usr/lib/sysimage/dnf
Feedback
Benefit to Fedora
- The RPM and DNF databases describe the state of (primarily)
/usr. Storing these databases in/usrwill more easily facilitate OS rollback, without affecting/var.
- Helps align Fedora variants with each other
- rpm-ostree based systems (including CoreOS, IoT, Silverblue, Kinoite) already use
/usr/lib/sysimagefor rpmdb.
- rpm-ostree based systems (including CoreOS, IoT, Silverblue, Kinoite) already use
- Consistency with another RPM-based distro, (open)SUSE has made this change
Scope
- Proposal owners:
- Other developers:
- changes in rpm and dnf-data packages
- create the new path instead of old
- create symlinks for the old path to new path
- changes in SElinux policy
- changes in rpm and dnf-data packages
- Release engineering: #Releng issue 10441
- Policies and guidelines: N/A (not needed for this Change)
- Trademark approval: N/A (not needed for this Change)
- Alignment with Objectives:
Upgrade/compatibility impact
Change will be applied on upgrades to Fedora 36.
How To Test
- Clean install or upgrade an existing Fedora system
- Note the changed database paths (new location) and symlinks in the old location
- Check that
rpmanddnfcommands work as expected, e.g.
dnf history rpm -qa
User Experience
Users will notice:
- symlinks in the old locations for the databases, pointing to the new locations;
- paths existing in the new locations.
Otherwise, the change should be invisible to users.
Dependencies
rpm-ostreeprobably should make/usr/share/rpma symlink to/usr/lib/sysimage/rpmrather than the reverse, as it is currently.
Contingency Plan
- Contingency mechanism: Revert the change, try again the next Fedora release.
- Contingency deadline: Beta freeze
- Blocks release? Yes
