In GRUB terms, sda means ahci0. 1 means msdos1, or gpt1, depending - on whether I am using MBR or GPT partitioning. Thus, /dev/sda1 is GRUB is (ahci0,msdos1) or - (ahci0,gpt1). In my case, I use MBR partitioning so it's (ahci0,msdos1). - 'msdos' is a GRUB name simply because this partitioning type is traditionally used by MS-DOS. - It doesn't mean that you have a proprietary OS. - </p> - - <p> - Trisquel doesn't keep the filenames of kernels consistent, instead it keeps old kernels and - new kernel updates are provided with the version in the filename. This can make GRUB payload - a bit tricky. Fortunately, there are symlinks /vmlinuz and /initrd.img - so if your /boot and / are on the same partition, you can set GRUB to boot from that. - These are also updated automatically when installing kernel updates from your distributions - apt-get repositories. - <b> - Note: when using <a href="">jxself kernel releases</a>, - these are not updated at all and you have to update them manually. - </b> - </p> - - <p> - For the GRUB payload grubtest.cfg (in the 'Load Operating System' menu entry), we therefore have (in this example):<br/> - <b>set root='ahci0,msdos1'</b><br/> - <b>linux /vmlinuz root=UUID=3a008e14-4871-497b-95e5-fb180f277951</b><br/> - <b>initrd /initrd.img</b> - </p> - - <p> - Optionally, you can convert the UUID to its real device name, for example /dev/sda1 in this case. - sdX naming isn't very reliable, though, which is why UUID is used for most distributions. - </p> - - <p> - Alternatively, if your /boot is on a separate partition then you cannot rely on the /vmlinuz and /initrd.img symlinks. - Instead, go into /boot and create your own symlinks (update them manually when you install a new kernel update).<br/> - $ <b>sudo -s</b> (or <b>su -</b>)<br/> - # <b>cd /boot/</b><br/> - # <b>rm -f vmlinuz initrd.img</b><br/> - # <b>ln -s <u>yourkernel</u> ksym</b><br/> - # <b>ln -s <u>yourinitrd</u> isym</b><br/> - # <b>exit</b> - </p> - - <p> - Then your grubtest.cfg menu entry (for payload) becomes like that, for example if / was on sda2 and /boot was on sda1:<br/> - <b>set root='ahci0,msdos1'</b><br/> - <b>linux /ksym root=/dev/sda2</b><br/> - <b>initrd /isym</b> - </p> - - <p> - There are lots of possible variations so please try to adapt. - </p> - - </div> - - <div class="subsection"> - <h3 id="example_modifications_parabola">Parabola GNU/Linux-libre</h3> - - <p> - You can basically adapt the above. Note however that Parabola does not keep old kernels still installed, and the file names - are always consistent, so you don't need to boot from symlinks, you can just use the real thing directly. - </p> - </div> - - <p> - <a href="#pagetop">Back to top of page.</a> - </p> - - </div> - - <div class="section"> - - <p> - Copyright &copy; 2014, 2015 Leah Rowe &lt;;<br/> - Permission is granted to copy, distribute and/or modify this document - under the terms of the GNU Free Documentation License, Version 1.3 - or any later version published by the Free Software Foundation; - with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. - A copy of the license can be found at <a href="../gfdl-1.3.txt">../gfdl-1.3.txt</a> - </p> - - <p> - Updated versions of the license (when available) can be found at - <a href=""></a> - </p> - - <p> - UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE - EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS - AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF - ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, - IMPLIED, STATUTORY, OR OTHER.
