  5. #        version: 1.2.3, 29-jun-2019, by eibgrad
  6. #        purpose: mount usb drive(s)/partition(s)
  7. #    script type: startup (autostart)
  8. #  compatibility: ext2, ext3, ext4, fat, fat32
  9. #   installation:
  10. #     1. enable jffs2 (administration->jffs2)
  11. #     2. enable syslogd (services->services->system log)
  12. #     3. set services->usb->usb support options as follows:
  13. #          core usb support = enable
  14. #          usb storage support = enable
  15. #          automatic drive mount = disable
  16. #     4. install usb drive(s) and reboot
  17. #     5. use shell (telnet/ssh) and blkid utility to determine uuid(s)
  18. #     6. use shell (telnet/ssh) to execute one of the following commands:
  19. #          curl -kLs bit.ly/ddwrt-installer|tr -d '\r'|sh -s VDZ32r2D startup
  20. #        or
  21. #          wget -qO - bit.ly/ddwrt-installer|tr -d '\r'|sh -s VDZ32r2D startup
  22. #     7. use vi editor to modify script w/ your preferred options and
  23. #              mounting points:
  24. #          vi /jffs/etc/config/ddwrt-mount-usb-drives.startup
  25. #     8. reboot
  26. #    limitations:
  27. #      - ntfs is NOT supported at this time
