Bismillah,

Alhamdulillah, saya berkesempatan menuliskan pengalaman saya menggunakan sysupgrade yang merupakan program yang berfungsi untuk melakan upgrade system OpenBSD. Pada contoh ini, saya menggunakan versi snapshot, sehingga upgrade nya ke snapshot terbaru.

Menjalankan perintah sysupgrade. Sebagaimana terlihat, sysupgrade ini mendownload fileset (file instalasi), kemudian langsung reboot dan menjalankan proses upgrade. Proses download ini bervariasi lamanya, tergantung speed bandwith mesin kita.

Tanggal hari saat proses upgrade ini. Semoga tulisan ini bermanfaat, terutama bagi yang baru mengenal OpenBSD, bahwa OpenBSD ini sangat user friendly, sangat mudah di gunakan, proses upgrade nya pun mudah pula.

Alhamdulillah
