rockylinuxNetwork-scripts deprecation in Rocky Linux 9 affecting ifcfg persistence
Transition to NetworkManager Rocky Linux 9 removes legacy network-scripts by default, shifting primary interface management to NetworkManager. In previous versions, manual edits to files in /etc/sysconfig/network-scripts/ were often sufficient to define static IP configurations that persisted across reboots via the network service. Configuration Sync Uncerta
PostgreSQL service on Rocky Linux: configuring StopWhenUnneeded to control idle connections
PostgreSQL service on Rocky Linux: configuring StopWhenUnneeded to control idle connections The goal is to ensure that idle PostgreSQL connections are released when the systemd service is stopped or restarted, thereby reducing the risk of connection pool exhaustion under variable workloads. Currently the default max_connections is 100, idle_in_transaction_se
Systemd socket activation application support limits for zero-downtime upgrades
Systemd socket activation is frequently discussed as a path to zero-downtime application upgrades on Rocky Linux because the listening socket can stay open while the service binary is replaced. The documented requirement is that the application must accept the file descriptor from systemd rather than binding the port itself. For legacy binaries that do not s
Rocky Linux retry safety limits: atomic DNF payloads versus repeated RPM scriptlet writes
Rocky Linux uses DNF to manage packages, and its download layer retries transient network failures according to configured retry, timeout, and minrate values. Completed payloads are written to temporary files and renamed into place, which prevents duplicated or truncated package files on a re-attempted download. The unresolved boundary sits at the RPM transa
Diagnosing whether systemd LimitNOFILE or TasksMax caps cause connection pool exhaustion on Rocky Linux 8/9
Goal Determine whether per-service systemd resource ceilings — LimitNOFILE (file descriptors) or TasksMax (threads/processes) — are the first bottleneck hit when a connection pool exhausts on Rocky Linux 8 or 9. Constraints and uncertainty Rocky 9 defaults to cgroup v2 while Rocky 8 uses hybrid or v1 unless configured, changing how limits are enforced and ob
bridge for virtualisation stays in state DOWN - unable to get it up
Running Rocky 9.3, attempting to get a bridge for a public Range of IPs for use with Virtual machines. Same hardware used to run Centos 7.8 machine with it all working, am now trying to set it up the same with Rocky 9.3 # /etc/sysconfig/network-scripts/ifcfg-brpub0 (pointopoint, Hetzner Standard) DEVICE=brpub0 ONBOOT=yes TYPE=Bridge BOOTPROTO=none IPADDR=xxx
Speakup Text Mode or Orca Graphical Mode for Rocky Linux Installs on Uncertain Hardware
Rocky Linux offers two documented accessibility paths in its Anaconda installer, and a deployment plan for blind and low-vision users has to commit to one before the capabilities of every target machine are known. The goal is to standardize a single installation procedure that stays dependable across mixed hardware. The text-mode console can be made accessib
DNF module stream cache expiration behavior with metadata_expire
Context Rocky Linux 9.2 and later use DNF with modular package streams, where dnf module list displays available streams and profiles. The DNF configuration directive metadata_expire (default 6h) controls how long repository metadata is considered fresh before a forced refresh. Goal Understand whether the metadata_expire timer applies uniformly to both base
