[OpenIndiana-discuss] pool messup

[Roy Sigurd Karlsbakk]

Persistent mapping is disabled, and has been for some time. lsiutil shows no persistent mappings. The drives are a varity of makes. The system has been the same since I reinstalled it a month or two back.

I all pedagogikk er det essensielt at pensum presenteres intelligibelt. Det er et elementært imperativ for alle pedagoger å unngå eksessiv anvendelse av idiomer med fremmed opprinnelse. I de fleste tilfeller eksisterer adekvate og relevante synonymer på norsk.
