    Why comes Ubuntu with a recovery mode?

    Is it possible to remove the recovery mode?

    What reason do you have for removing recover mode?

    Removing recovery mode may well be an action you can not recover from.

    A few lines about the uses of recover mode via Ubuntu wiki

    Re: Why comes Ubuntu with a recovery mode?

    Perhaps the OP is worried about the fact that recovery mode allows for any user to log in and access the file system as root...this can be avoided by setting a root password, though...

    And completely overridden with a boot disc/drive.

    Poeha, a couple of threads concerning root access passwords and recovery mode that have been asked in the last few weeks.

    aks root password at failsafe boot

    Recovery root command-line doesn't require password?

    The may answer some of your worries but if not then ask more questons.

    Physical access trumps all other permissions.

    This?:
    Code:
    /boot/grub/grub.cfg
    Learning how to use chroot before making these changes would probably be a good idea.

    But what is logic behind the recovery/failsafe mode? Why is this choice/feature "defended" by refering to "Physical access is root access" arguments. I want a Linux system with restricted policies. I assume an alternate install, with a complete encrypted os is the way to go?

    An encrypted home, is the only way to protect your personal data. If someone has physical access to your computer, they can access unencrypted data, no matter what restrictions and policies you put in place.

    I've serviced and repaired computer systems for years, a password or restrictive policies has never stopped me from doing what needs to be.

    For at least two minutes, unless it's a laptop, in which case it would be more like 5 minutes (a few screws will need to be removed).

    As mentioned encrypting your data is probably the best approach.
