Rocky Linux 10+ Knowledge Patch

Claude's baseline knowledge covers Rocky Linux through 9.3. This skill provides changes from 9.5 (2024) onwards.

Quick Reference

Breaking Changes in Rocky Linux 10.0

What Changed	Old (RL 9.x)	New (RL 10+)
Package streams	dnf module enable/install	Direct dnf install pkg-version
Version discovery	dnf module list <pkg>	dnf repoquery <pkg>
Redis	dnf install redis	dnf install valkey
Redis CLI compat	Built-in	dnf install valkey-compat-redis (Plus repo)
Deprecated kernel features	Enabled by default	Disabled; add rh_waived to re-enable
RPM version sorting	sort (incorrect)	rpmsort (RPM-aware)

DNF Modularity Removed

DNF 5 removes modularity entirely. All dnf module commands are gone:

# RL 9.x (no longer works in 10)
dnf module enable nginx:1.14
dnf module install nginx:1.14

# RL 10+ (direct install)
dnf repoquery --available nginx # discover versions
dnf install nginx-1.26.3        # install specific version

See references/package-management.md for full migration table and patterns.

Valkey Replaces Redis

Redis is removed. Valkey 8.0 (API-compatible fork) is the replacement:

dnf install valkey
systemctl enable --now valkey

For redis-cli/redis-server command compatibility:

dnf install valkey-compat-redis # from Plus repo
redis-cli ping                  # works as alias to valkey-cli

See references/service-changes.md for configuration paths and migration details.

rpmsort — RPM Version Sorting

rpm -q kernel | rpmsort # correct: 6.12.0-13 before 6.12.0-130
rpm -q kernel | sort    # wrong: 6.12.0-130 before 6.12.0-13

rh_waived Kernel Argument

Deprecated/insecure kernel features are disabled by default. Re-enable for legacy workloads:

sudo grubby --update-kernel=ALL --args="rh_waived"

See references/service-changes.md for details on when this is needed.
