YUMI-UEFI new options!
« on: March 10, 2021, 06:04:49 PM »
Yumi-UEFI (as of ver has a new option to use "Try Unlisted Iso", which works very well, especially on new so-called "UEFI-ONLY" machines.

While I'm not interested in multi-booting iso's with it, it can serve as a "poor man's install" for the 64-bit TC iso's if you don't want to create a bootable 64-bit uefi-only stick yourself manually.

The end result - by using the "Try Unlisted Iso" - is that of a read-only filesystem in ram that emulates a CD boot environment naturally.

Which means that every time you boot, if you have boot options to pass to the system, you'll be doing so each and every time you boot at the TC grub menu prompt.  Like a CD environment.  Or your other TC options for persistence like home=xXxX, restore=xXxX etc.  See the TC documentation for that.

Previously, Yumi-Uefi only attempted to make a *writable* version of TC when you selected it as a supported distribution, but made mistakes rewriting TC's own grub menu, which left if unbootable!  Which means you had to know where to look for the error and manually correct it yourself - which most newbs don't know about.

Of course being 64 bit, the standard release means you'll be in a framebuffer environment (NOT xvesa!), and typically at a non-native video resolution.  That may work fine for what you need to do, although it is beyond the scope of this message if you want to install a full Xorg, different window managers etc.

And of course, since YUMI is NOT part of TC directly, if it breaks, you get to keep both pieces.

But what I'm trying to get at here is that by using the NEW feature that Yumi-Uefi has of "Try Unlisted ISO", is that in the end you'll be booting into a CD read-only type of environment, on uefi-only machines, yet still be on the same page with most of us since it is booting an unchangeable iso once you get past the front-end that Yumi-Uefi provides.

For some, the need for this is questionable since there are unix tools to make your own bootable stick for UEFI-Only, which Juanito and others go into great lengths to support.

But for the "poor man's install", the *end result* of using Yumi-Uefi with the try-unlisted-iso option, means that we can assume that you are using a CD type of environment, (booting an iso directly) and not really worry or point the finger at Yumi being the culprit for errors.  Doesn't matter now.  What does is simply how you get to know and love how to handle TC proper in normal use.
