        #? 1

        The following information has been given:

            Portugal
            mainland

        Therefore TZ='Europe/Lisbon' will be used.
        Local time is now:      Sun Aug  9 17:36:05 WEST 2016.
        Universal Time is now:  Sun Aug  9 16:36:05 UTC 2016.
        Is the above information OK?
        1) Yes
        2) No
        #? 1

        You can make this change permanent for yourself by appending the line
            TZ='Europe/Lisbon'; export TZ
        to the file '.profile' in your home directory; then log out and log in again.

        Here is that TZ value again, this time on standard output so that you
        can use the /usr/bin/tzselect command in shell scripts:
        Europe/Lisbon

        <p>First we will discover block id (UUID) of

        blkid list all while vol_id --uuid /dev/sdb1 returns
        only uuid. Add all block ids to the end of file
        /etc/fstab;

        <pre>
        # blkid >> /etc/fstab

        <p>Read <a href="http://linux-audit.com/securing-mount-points-on-linux/" title="Securing mount points">Securing mount points</a>,
        and edit /etc/fstab according to your disk layout. Blocks with uuid will later be created at <a href="../tools/lvm.html">lvm</a>.</p>

        <p>Pass option control in wich order fsck checks devices. If is
        a multiple partition scheme; 1 for root, 2 for others or 0 to
        disable fsck. In this example fsck in usr partition is disable,
        initram file system mounted on boot making impossible to run fsck.</p>
