[09:23] <FourDollars> cjwatson: It seems that grub-efi-amd64-signed doesn't support uuid search for vfat file system. Right?
[09:31] <xnox> for vfat/ntfs do not support linux filesystem UUID, instead use label
[09:32] <FourDollars> xnox: Got it, thanks a lot.
[09:32] <xnox> the vfat/ntfs labels are symlinked into /dev/disk/by-uuid/ which may suggest otherwise.
[09:33] <xnox> no problem =)
[09:33] <FourDollars> xnox: Are you sure that grub-efi-amd64-signed supports label search for vfat file system?
[09:33]  * FourDollars is oging to try it.
[09:33] <FourDollars> s/oging/going/
[09:34] <xnox> xnox: i know that grub supports label search. But I have not yet tried any efi stuff.
[09:36] <FourDollars> xnox: I use grub-install from quantal. It puts 'search.fs_uuid 1F4E-FBA8 root hd0,msdos1' on my USB drive.
[09:37] <FourDollars> xnox: So I think grub also supports uuid search for vfat.
[09:37] <FourDollars> xnox: But grub-efi-amd64-signed might have limited functionalities.
[10:55] <cjwatson> FourDollars: I don't see a particular reason it shouldn't support that; it seems to have all the relevant modules.  Sounds like a bug.
[10:55] <cjwatson> (Both label and UUID.)
[10:59] <FourDollars> cjwatson: Thanks for your reply.

[17:59] <bizhanMona> HI is this a right place to ask about kickseed/preseed?thx
[17:59] <cjwatson> Yes
[18:00] <cjwatson> But it's nearly dinnertime here so be quick
[18:01] <bizhanMona> oh okay then please go ahead have your dinner, I have just started to process of understanding what it is and will have lot us of questions in future. Thank you.
[18:03] <cjwatson> OK, sure.  Quick mental model: preseed is a way to set a bunch of values in a database which is consulted by the installer during operation and can provide answers to what might otherwise be interactive questions.  kickseed is a compatibility layer for the Red Hat Kickstart format that translates things into preseeding at the very start of the installer
[18:03] <cjwatson> You can mix and match them (via the Ubuntu-specific 'preseed' command extension to Kickstart)
[18:04] <bizhanMona> oh great, because I know about the Redhat kickstart so I can use the same kick start file, (I hope) then.
[18:06] <cjwatson> Well, it will provide a starting point at least; it probably won't be complete
[18:06] <bizhanMona> okay great to know I can always come here for help. THanks so much.
[18:06] <cjwatson> The idea was more to get people over the initial hurdle than to provide compatibility with every detail (though I do add details if they aren't too painful to translate)
