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.

#? 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:

<h2 id="fstab">1.2.5. File system table</h2>
<p>First we will discover block id (UUID) of
<a href="install.html#step2">target partition</a>,
blkid list all while vol_id --uuid /dev/sdb1 returns
only uuid. Add all block ids to the end of file
/etc/fstab;
</p>
<pre>
# blkid >> /etc/fstab
</pre>
<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>
