77 <h3><a name="whatis"></a><a href="#toc">What is Grml?</a></h3>
79 <p>Grml is a bootable CD (Live-CD) based
80 on <a href="http://www.debian.org/">Debian</a>. It is not
81 necessary to install anything to a harddisk. Grml includes a
82 collection of GNU/Linux software especially for system
83 administrators. It specializes on administrative tasks like
84 installation, deployment and system rescue.</p>
86 <h3><a name="flavours"></a><a href="#doc">What are grml32 / grml64 and grml96?</a></h3>
89 <li>grml32: 32bit version (kernel and userspace)</li>
90 <li>grml64: 64bit version (kernel and userspace)</li>
91 <li>grml96: multi boot version (featuring grml32 and grml64 on one ISO)</li>
94 <p>Unless you've a good reason to really choose the 32bit flavour we
95 strongly encourage you to use either the grml64 or the grml96
98 <p>Please notice that this schema was introduced starting with Grml
99 release 2011.12. Until then grml96 didn't exist and grml32 was known as
102 <h3><a name="get"></a><a href="#toc">Where do I get Grml?</a></h3>
104 <p>Grml is open source, you can download it from the mirrors
105 listed at <a href="/download">grml.org/download/</a>.</p>
107 <h3><a name="whatmeans"></a><a href="#toc">What does Grml mean?</a></h3>
109 <p>Grml comes close to 'argl' or 'grrr' in English. People use
110 this when they want to express their dissatisfaction with
111 software (amongst other things).</p>
113 <h3><a name="releasename"></a><a href="#toc">What about the release name?</a></h3>
115 <p>Codename of Grml 2011.12 is "Knetch Rootrecht". It's a wordplay on
116 <a href="http://en.wikipedia.org/wiki/Companions_of_Saint_Nicholas">Knecht
117 Ruprecht</a>, which translates as Farmhand Ruprecht or Servant
120 <h3><a name="requirements"></a><a href="#toc">Requirements for running Grml</a></h3>
124 <li>Intel-compatible CPU (i586 or later, preferably Pentium class or higher)</li>
126 <li>>=128MB of RAM (>=256MB recommended)</p>
128 <li>either a bootable CD-/DVD-ROM drive,
129 a <a href="#usbboot">USB-boot capable system</a> or a
130 network card for booting via network/PXE (check
131 out <a href="#terminalserver">grml-terminalserver</a>)</li>
135 <h3><a name="accessibility"></a><a href="#toc">What does accessibility at Grml mean?</a></h3>
137 <p>The Grml kernel includes support for speakup. For software,
138 brltty and espeakup are included.</p>

172 <h3><a name="password"></a><a href="#toc">What are the passwords of users on Grml?</a></h3>
174 <p>There are no default passwords - all accounts are locked by
175 default for security reasons. Even local logins are not
176 possible (unless you set a password or create new user
177 accounts as root). You can create valid passwords using "sudo
178 passwd [username]" from the shell individually.</p>
180 <h3><a name="version"></a><a href="#toc">How do I find out the version of Grml</a></h3>
182 <p>Run 'grml-version' or use the following command:</p>
185 $ cat /etc/grml_version</pre>
187 <h3><a name="language"></a><a href="#toc">How do I change the language/keyboard settings?</a></h3>
189 <p>By default Grml uses english settings. But it is possible to
190 change the settings via using either the bootparam(s) lang,
191 keyboard and xkeyboard or via executing grml-lang when Grml is
192 already running. Usage examples:</p>
195 grml lang=de # enter this at the bootprompt and you will get
196 # german keyboard layout and german $LANG, $LC_ALL,
198 grml keyboard=de xkeyboard=de lang=at # enter this at the bootprompt
199 # and you will get german keyboard and austrian
201 % grml-lang de # enter this in the shell to switch keyboard layout
202 # and $LANG settings in a running Grml system
205 <p>Note: run grml-setlang to get a dialog based frontend for
206 /etc/default/locale. Run grml-setkeyboard to get a dialog
207 based frontend for /etc/sysconfig/keyboard.</p>
210 <h3><a name="wms"></a><a href="#toc">Which window managers can I use?</a></h3>
212 <p>Starting with the 2011.12 release Grml provides <a
213 href="http://www.fluxbox.org/">Fluxbox</a> as window manager.</p>
215 <h3><a name="lvm"></a><a href="#toc">Where are my LVM devices?</a></h3>
217 <p>LVM (Logival Volumes) is <strong>not</strong> started by default to
218 avoid any possible damage to your data. To get access to present LVM
219 devices just execute:</p>
222 # /etc/init.d/lvm2 start
225 <p>If you want to enable LVM by default just boot using the 'lvm'
226 bootoption which automatically enables LVM.</p>
228 <h3><a name="swraid"></a><a href="#toc">Where are my Software-RAID devices?</a></h3>
230 <p>Software-RAID (usually known as the mdadm stuff) is
231 <strong>not</strong> started by default to avoid any possible damage to
232 your data. To get access to present SW-RAID devices just execute:</p>
235 # /etc/init.d/mdadm-raid start
238 <p>If you want to enable SW-RAID by default just boot using
239 the 'swraid' bootoption which enables automatic assembling of
240 software raid arrays.</p>
242 <a name="terminalserver"></a>
243 <h3><a name="booting"></a><a href="#toc">Which ways exist to boot Grml?</a></h3>
245 <!-- TODO: needs rework -->
247 <p>Of course running from CD/DVD is a common way to boot
248 Grml. But Grml provides many more ways to boot:</p>
250 <p>It is possible to boot Grml via USB (e.g. USB stick or
251 harddisk), firewire, or running from a Compact Flash disk. It
252 works out of the box; you don't need to modify anything. Check
253 out <a href="http://wiki.grml.org/doku.php?id=usb">the usb
254 webpage in the grml-wiki</a> for more details.</p>
256 <p>Your computer can not boot from CD-ROM but provides a
257 floppy disk? Take a look
258 at <a href="http://btmgr.sourceforge.net/">btmgr</a>, <a href="http://ubcd4win.com/faq.htm#floppy">ubcd4win</a>
259 or <a href="http://linux.simple.be/tools/sbm">sbm</a>. They
260 provide support for booting from CD-ROM via a special floppy
263 <p>grml-terminalserver makes it possible to boot your system
265 using <a href="http://en.wikipedia.org/wiki/Preboot_Execution_Environment">PXE</a>
266 (Preboot Execution Environment). If your network card does not
267 provide support for booting via PXE you can still boot it
268 either using the provided grub image by grml-terminalserver
269 (for example via floppy drive) or
270 using <a href="http://etherboot.org/wiki/index.php">gPXE</a>.

275 <h3><a name="timezone"></a><a href="#toc">How do I configure
276 timezone on my Grml system?</a></h3>
278 <p>Available bootoptions relevant in live-cd mode:</p>
281 <li>utc: set UTC, if your system clock is set to UTC (GMT)
282 <li>gmt: set UTC, if your system clock is set to UTC (GMT) [like bootoption utc]
283 <li>tz=$option: set timezone to corresponding $option, usage example:

293 <h3><a name="hdinstall"></a><a href="#toc">Is it possible to install Grml to harddisk?</a></h3>
295 <p>Short anwer: No.</p>
297 <p>If you want to get a plain Debian system take a look at <a
298 href="/grml-debootstrap/">grml-debootstrap</a>.</p>
300 <p>Long(er) answer: yes it's possible to install Grml. But it's not
301 supported and you'll be on your own. That's why we decided to make it
302 not-so-obvious. If you really know what you're doing you'll find out on
303 your own. Reminder: use <a
304 href="/grml-debootstrap/">grml-debootstrap</a> or <a
305 href="http://www.debian.org/">Debian Installer</a> instead.</p>

312 <p>If you want to get details about the provided packages and the

317 <h3><a name="zsh"></a><a href="#toc">Why is Zsh the default shell?</a></h3>
319 <p>Short answer: because <a href="/zsh/">Zsh rocks</a>, really!</p>
321 <p>Long(er) answer: If you don't know Zsh take a look the <a
322 href="/zsh/">Grml Zsh reference card</a>.</p>
324 <p>If you are a Bash user and don't know Zsh yet, don't be
325 afraid. Bash is largely a subset of Zsh and you don't have to
326 throw away your knowledge about shell stuff.</p>
