Well I feel like a fool, but I owe you one anyways. As noted in my message, isohybrid was one of the first things I tried, and it seemed to work, but the installer would bail saying can't find file, seemingly referring to the squashfs file. Now I'm pretty sure it was saying it couldn't find my kickstart file. I'd modified the menu to say ks=cdrom:. I restored and tried the default install option, works fine. Setting my ks line to ks=hd:LABEL . . . also works fine. My custom ks and packages and everything work straight from the initial menu. If anyone could fill me in on exactly what that partition structure on the official images is doing though, I'd be curious to know. -Matt On Tue, Jan 13, 2015 at 10:29 PM, Alfred von Campe <alfred at von-campe.com> wrote: > On Jan 13, 2015, at 23:16, Matt <matt at mattlantis.com> wrote: > >> I guess I could phrase my question as "Given that the default image >> for 6.6 and 7.0 do this, how do I make custom media that does it to?" >> >> When I make custom media, it only works off an actual DVD. > > Have you tried /usr/bin/isohybrid on the ISO file? > > Alfred > > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos
