Ogni 6 mesi viene rilasciata una nuova versione di OpenBSD. Nel momento in cui scrivo, ad esempio, è disponibile su http://openbsd.org la versione 7.6.
Per aggiornare la propria installazione, è necessario eseguire semplicemente il comando “sysupgrade”, tante volte quante sono le versioni arretrate mai installate. Nel mio caso, ero fermo alla versione 7.3, quindi ho dovuto eseguire il “sysupgrade” per ben 3 volte. Al termine di ogni ciclo di upgrade avviene il reboot della macchina.

Una volta installata l’ultima versione, per aver il sistema completamente aggiornato, è necessario installare eventuali patch emesse per gli eventuali bug riscontrati, sia di sistema operativo (syspatch) e sia relativo alle applicazioni installate (pkg_add -u)
doas syspatch
doas pkg_add -u
Raccomanderei anche di installare sysclean e di eseguire qualcosa come
doas sysclean | egrep '^/usr/(lib|bin|sbin|include|X11R6|share)'|xargs -n 1 -t doas rm -rf
Questo rimuoverà tutti i binari, librerie etc non più necessari e manterrà la macchina un pò pulita
