Fa'asa'olotoina le NetBSD 9.0 faiga fa'aoga

Avanoa fa'amalologa tele faiga fa'aoga NetBSD 9.0, lea o loʻo faʻatinoina ai le isi vaega o foliga fou. Mo le utaina saunia fa'apipi'i ata 470 MB le tele. Ole faʻasalalauga NetBSD 9.0 o loʻo avanoa aloaia ile fausiaina mo 57 fausaga fausaga ma 15 aiga CPU eseese.

E ese'ese, o lo'o i ai 8 pito sili ona lagolagoina o lo'o avea ma autu o le NetBSD's development strategy: amd64, i386, evbarm, evbmips, evbppc, hpcarm, sparc64 ma xen. 49 ports e fesoʻotaʻi ma PPU e pei ole alpha, hppa, m68010, m68k, sh3, sparc ma vax o loʻo faʻavasegaina i le vaega lona lua, i.e. o lo'o lagolagoina pea, ae ua leiloa lo latou taua po'o le le lava le aofa'i o tagata atia'e e fiafia i latou atina'e. O le tasi uafu (acorn26) o loʻo aofia i le vaega lona tolu, lea e aofia ai ports e le mafai ona faʻaogaina e agavaa mo le aveeseina pe a leai ni tagata fiafia e fiafia i latou atinaʻe.

Ki faaleleia NetBSD 9.0:
