221<title>Partitioning the Drive</title>
222<body>
223
184</p> 224<p>
185 225Now that we have a mount point, it's time to partition the drive. This is done
186<pre caption="Remounting a partition in read-write mode"> 226with the <c>sysinstall</c> command:
187# <i>ount -u -o rw /mnt/ufs.1</i>
188</pre>

229<pre caption="Running the sysinstall command to fdisk the drive">
230# <i>sysinstall diskPartitionEditor diskPartitionWrite</i>
231</pre>
232
233<p>
234We recommend that you use the default layout. Press enter at the dialog, then
235press <b>a</b> followed by <b>q</b> to accept the default layout. The next
236screen will present you with the option of a bootloader. For this option,
237choose "None" as we'll be installing the bootloader later on. Next comes the
238actual partition sizing and mount points.
239</p>
240
241<p>
242This next step also uses <c>sysinstall</c>, but with different arguments:
243</p>
244
245<pre caption="Running sysinstall to setup partition sizing and mount points">
246# <i>sysinstall diskLabelEditor diskLabelCommit</i>
247</pre>
248
249<p>
250Here, we'll refrain from using the automatic layout, and create one giant root
251partition, followed by a swap partition. Hit <b>c</b> to create a new
252partition. A dialog prompts you to enter a size. Go ahead and do so, using
253MB/GB for setting different sizes, or C for cylinders. For root, choose FS as
254the partition type, and set the mount point as <path>/mnt/gentoo</path>. <e>If
255you do not adjust the mount point, it will overwrite the FreeSBIE
256environment!</e> As <path>/boot</path> is not a separate partition, you'll
257need to disable soft-updates, or your system will not boot! To do so, use the
258arrow keys to navigate to your newly created partition, then hit the <b>s</b>
259key, until "Newfs" contains no <b>+S</b>. Now navigate the arrow keys until
260the "Disk" line is highlighted, and hit <b>c</b> again to create a swap
261partition. Generally, we recommend a swap space that is twice the size of your
262RAM. Choose SWAP as the partition type, and don't worry about soft-updates, as
263it does not apply to swap. Now we're finished, so hit <b>q</b> to finish the
264process.
265</p>
266
267<p>
268When choosing a different mountpoint than <path>/</path> for your partition,
269<c>sysinstall</c> will actually create a 'd' slice, which the bootloader won't
270boot from. To fix this, run the following:
271</p>
272
273<pre caption="Fixing the root partition letter">
274# <i>disklabel ad0s1 | sed 's/^ d:/ a:/g' | disklabel -w ad0s1</i>
275</pre>
276
277<p>
278This will finalize the partitioning process, and format the drive in UFS for
279FreeBSD to utilize. This will also mount the drive for you at the mount point
280specified earlier (<path>/mnt/gentoo</path>). You can verify this worked by
281running <c>mount</c>:

206Before chrooting into the newly-extracted stage, you first must obtain an
207up-to-date copy of the Gentoo/FreeBSD overlay. The easiest way to achieve this
208is to to get our latest snapshot which you then extract to
209<path>/mnt/gentoo/usr/local/portage</path>.
