  • Hogyan (És Miért) Telepítsünk Linuxot Chromebook-Ra
    Hogyan (és miért) telepítsünk Linuxot Chromebook-ra Crouton és Gallium OS a Chromebook-ot Linux laptoppá változtatja. J.M. PORUP (UK) - ARS Technica UK, 2017. június 19. Crouton: linuxos rágcsa a Chrome-os salátádhoz A Crouton (zsemlekocka) a 2016-os Acer Chromebook-unkra (itt veheted meg) kevesebb mint fél óra alatt települt és chroot-ként fut a Chrome OS mellett. A szellemes GitHub README szerint a projekt neve a „ChRomium Os Universal chrooT envirONment” rövidítése, és Debian Linux-ot és olyan leszármazottait, mint az Ubuntu és Kali Linux támogatja. A Crouton-t könnyű kipróbálni és megér egy estét babrálni vele. A Chromebook-ban lépj be fejlesztői (developer) módba, ami a legtöbbek számára annyi, hogy az Esc és a Refresh gombokat lenyomva kell tartani a bekapcsoló gomb megnyomásakor. Ezáltal a Chromebook-on helyileg tárolt adatok törlődnek (ha ne adj Isten egy felhőre kihegyezett gépen helyi adatokat tárolnál). Nyomj Ctrl-D-t, Enter-t és kb. öt percet várj a Chromebook törléséig. Ahogy developer módba kerültél, a Chromebook-od figyelmeztet, bármikor így indítasz, a géped sérülékeny lesz. David Schneider, a Crouton karbantartója, aki a Google-nak dolgozik, nem kapott engedélyt, hogy a cikk számára erről az Ars-nak beszéljen, a Crouton wiki-jében a biztonsági kompromisszumot így írja le: „A Dev mód alapból számos dolgot végez el, ami a biztonságot csökkenti, közte az ellenőrzött boot kikapcsolását, a VT2 [terminál] engedélyezését és lehetővé teszi a A Chromebook, a nem technikai beállítottságú felhasználónak adható jelszó nélküli rendszergazda héj elérését. Ez annyit jelent, hogy Crouton nélkül is, legbiztonságosabb eszköz és tagadhatatlanul baráti áron, cserébe a személyes tér ha dev módban vagy, bárki VT2-re válthat, bejelentkezhet rendszergazdaként és feladásáért: meg kell bíznod a Google-ban, ami az NSA Prism programjában részt billentyűzetfigyelőt telepíthet, majd visszaléphet anélkül, hogy észrevennéd.
