XTRV ROM και Init.d scripts

      • Διαφήμιση

    • Να φανταστώ ο λόγος είναι ότι δεν έχουμε πειράξει τον kernel των 7ριων ROMs, ώστε να υποστηρίζουν init.d. Σωστά George ?

      Νέα έκδοση S97SystemOptimizer script.

      Changelog:
      - Έγινε comment κώδικας που δεν λειτουργούσε.
      - Έγιναν comment τιμές σε SD Cards tweaks που ήδη έχουν προσδιοριστεί από άλλο script που τρέχει νωρίτερα (και αυτό το script της έκανε override).
      - Προστέθηκαν I/O queue tweaks, Kernel samepage merging, MCPS

      =============== Αυγ 22nd 2017, 5:23pm ===============
      Και συνεχίζουμε.

      Νέο /system/etc/sysctl.conf και sysctl_tweaks.


      Changelog:

      - Προστέθηκε η παράμετρος vm.overcommit_ratio στο sysctl.conf

      - Άλλαξε το sysctl_tweaks ώστε να εκτελεί την εντολή sysctl -p το οποίο στην συντριπτική πλειοψηφία των kernels πρέπει να φορτώνει ούτως ή άλλως τις τιμές του sysctl.conf, καθώς (δυστυχώς) ο κώδικας που είχε μέχρι στιγμής παρέπεμπε σε ανύπαρκτο init.d script (για την παράλειψη αυτή εδώ και εβδομάδες που ασχολείται με τα init.d scripts, o γράφων...αυτομαστιγώθηκε επανειλημμένως !!!).
