Opkg extras

  • This instruction extends Opkg functionality.
  • Follow the automated section for quick setup.
  • Save, restore and roll back Opkg profiles.
  • Support automatic and custom profiles.
  • Support RWM, overlay and extroot setup.
  • Identify user-removed/installed packages.
  • Restore automatically after firmware upgrade.
  • Upgrade all upgradable packages.
  • Find new configurations.
  • Wrap Opkg calls to provide a seamless invocation method.
  • Rely on UCI and backup defaults to store and manage profiles.
  • Identify package types with grep and find, and RWM with mount.
  • Support importing user-installed packages from Sysupgrade.
  • Use Hotplug to detect WAN connectivity and trigger profile restore.
  • Utilize lockfiles with lock to avoid race conditions and loops.
  • Perform reboot to apply changes after automatic profile restore.
  • Write and read non-interactive logs with Syslog for troubleshooting.
  • Fetch the default profile to restore and roll back from UCI, unless specified manually.
  • Take precedence for remove over install to avoid package conflicts while restoring profile.
  • Limit the operation scope to save time: remove installed, install missing, upgrade upgradable.
  • Process packages one by one to minimize resource consumption and avoid transaction failure.

rollback [<prof>] Roll back Opkg profile:
remove user-installed packages,
install user-removed packages,
skip upgraded packages.
upgr [<pkgtype>] Upgrade packages by type:
ai or none - all installed,
oi - overlay-installed.
export [<pkgtype>] Export packages by type:

wr - RWM-removed,
wi - RWM-installed,
or - overlay-removed,
oi - overlay-installed,
ur - user-removed,
ui - user-installed,
pr - profile-removed,
pi - profile-installed.
proc <cmd> < <pkgs> Process packages from stdin with the given sub-command.
