Question about edit to Beginners' Guide
I noticed your recent edits in the Beginners' Guide, where you stated that the --target parameter is required. The man page however states that it defaults to the current platform (should be sufficient for beginners). I also just tested this (at least for BIOS), and it seems to work fine without the parameter.
Can you explain why it is needed?
AFAIK in the initial release of grub 2.00 grub-install explicitly required the user to provide the --target parameter, but then in some later bzr snapshot grub-install tries to guess the platform. In my experience grub-install defaults to i386-pc (BIOS) target most of the time, even in case of x86_64-efi (UEFI) system. I suggest changing all grub-install commands across the wiki to use --target parameter to remove this confusion. -- Keshav Padram Amburay (talk) 15:21, 29 August 2013 (UTC)
- Ok, I understand, I thought the 'guessing' was more robust and failure-proof. Thanks for the reply! :) --Lonaowna (talk) 19:47, 29 August 2013 (UTC)
I noticed your recent changes to the Beginner's Guide on the 18th September, particularly around EFISTUB. You have certainly managed to reduce the number of lines on the page which is good.
However I wanted to confirm that the user really is no longer required to reload the efivars module before chroot ? I read your entry about Jones' new and improved efibootmgr and this should mean that the module reload is no longer required, but has the fork been mainlined into the Arch core repository yet ?
Also is there a way to simplify the call to efibootmgr especially to be easier for new Archers or at least some way to make it easier. For example : "root=/dev/sdaX may be a little more welcoming than "root=PARTUUID=xxxxxxxxxxxxxxxxx". What do you think ? Thanks. Kal (talk) 19:41, 18 September 2013 (UTC)
From core/linux-3.11.1-1 onwards efivars module is not even compiled in the kernel https://projects.archlinux.org/svntogit/packages.git/commit/trunk?h=packages/linux&id=ebf4d782ffe29e3b00e93011a493cbedffbd7415 . This is a deliberate change made by the devs http://email@example.com/msg21788.html . THis chaneg was made only after new efibootmgr moved to core, see 'Upstream URL' in https://www.archlinux.org/packages/core/x86_64/efibootmgr/ .
Reg /dev/sdaX vs PARTUUID, sdaX is very ambiguous and not recommended even in case of bios boot. IN case of UEFI boot, since we are already using GPT, PARTUUIDs are the best FS-independent unambiguous way of specifying a partition. You can even mention (FS) UUID here but in case of GPT I recommend PARTUUID. Even if they are no Archers, they should not be simply conpy-pasting the commands from this page. They should understand what efibootmgr is, what PARTUUID is etc. and then type the command on their own. My intention is not be more welcoming to newbies. I just don't want them to come back later complaining sdaX is not the partition they want when they make some changes in their system and then it refuses to boot due to using ambiguous sdaX. -- Keshav Padram Amburay (talk) 04:43, 19 September 2013 (UTC)
