[lubuntu-users] Can live USB version number be included at boot?

[scrooyahoo]

From a endusers perspective it would be nice if a full version could be 
included


I now have several sticks

16.04.0 32, 64 bit
16.04.1 32 bit and pae

But when they boot they all look the same.

It can save many people a lot of time if this is displayed BEFORE 
loading into the live environment.


I put stickers on them, and still it is a hassle.

Now i'm sure it also be a hassle to add such a change, but it would 
improve the user experience.


Also when having multiboot where it is not possible to read from a 
sticker what is currently loaded. :-)

I have had the same issue on vanilla Unity Ubuntu.  UK English
randomly switches to US English (I think).

I added a 2nd layout -- US and UK -- and when it happens, I use the
status-bar indicator or the keystroke and manually switch to US and
then again to UK.

It's not a fix, but as a workaround, it suffices.

Any other thoughts?


I have no further ideas, at present.

Perhaps applications make unwarranted assumptions on the keyboard layout 
to use, or perhaps set it to their own liking.


I have had many cases, where (though the installed keyboard layout is 
dvorak), when in an unusual situation (such as recovering in terminal 
mode from an unexpected error), the terminal-mode software would assume 
(and enforce) a qwerty layout.

Dear mailing list and Aere,

the problem persists. Sometimes when I switch applications the keyboard
configuration changes. I only have one keyboard layout installed.

Using IBUS Preferences and disabling the keyboard shortcut to change layouts
(despite I only have one) makes no difference. Enabling the keyboard layout
handler on my taskbar has no effect neither.

Any other thoughts?

Re: [lubuntu-users] Is it possible to 'multi boot' ISO's with MKUSB?

[Narcis Garcia]

I walk with 10~20 ISO files in a single USB memory pendrive to perform
lots of installations and hardware tests with different GNU/Linux
distribution.

Grub has been my best option, but it's very tricky to properly configure
grub.cfg for each different OS.

Something I seldom see mentioned, but I use a lot, is Linux systems
_installed_ onto USB stick.

No, you can't install from them, but they are very useful for system recovery.

There are 2 ways to do it.

[1] Use a diskless PC, or disconnect your hard disk.

This is fiddly.

[2] Use a VM.

VirtualBox is free and lets you assign a physical disk drive to a VM.
It's much harder than in VMware but it does work.

http://www.sysprobs.com/access-physical-disk-virtualbox-desktop-virtualization-software

Read the comments!

Every time you want to run the VM, you must take ownership of the USB
device's entry in /dev

E.g.

chown /dev/sdc lproven:lproven

N.B. May require sudo.

Then it works. If you don't do this, the VM won't start.

Ubuntu 16.04 will not install on an 8GB USB key, but Lubuntu will.  It
puts GRUB in the MBR of the key, so it boots like any other disk.

Hints:

* Partition the disk as usual. I suggest no separate /home but it's up
to you. A single partition is easiest.

* Format the / partition as ext2 to extend flash media life (no
journalling -> fewer writes)

* Add ``noatime'' to the /etc/fstab entry for the root volume --
faster & again reduces disk writes

* No swap. Swapping wears out flash media. I install and enable ZRAM
just in case it's used on low-RAM machines:

http://askubuntu.com/questions/174579/how-do-i-use-zram

* You can add VirtualBox Guest Additions if you like. The key will run
better in a VM and when booted on bare metal they just don't run.

I then update as normal.

You can update when booted on bare metal, but if it installs a kernel
update, then it will run ``update-grub'' and this will add entries for
any OSes on that machine's hard disk into the GRUB menu. I don't like
this -- it looks messy -- so I try to only update inside a VM.

I usually use a 32-bit edition; the resulting key will boot and run
64-bit machines too and modern versions automatically run PAE and use
all available RAM.

Sadly my Mac does not see such devices as bootable volumes, but the
keys work on normal PCs fine.

Windows can't see them as it does not natively understand ext* format
filesystems. If you wish you can partition the drive and have an exFAT
data partition as well, of course.

I also install some handy tools such as additional filesystem support
(exFAT, HFS etc.), GParted, things like that.

I find such keys a handy addition to my portable toolkit and have used
them widely.

If you wish and you used a big enough key, you could install multiple
distros on a single key this way. But remember, you can't install from
them.

I've also found that the BootRepair tool won't install on what it
considers to be an installed system. It insists on being installed on
a live installer drive.

If you want to carry around lots of ISO files and choose which to
install, a device like this is the easiest way:

Re: [lubuntu-users] Is it possible to 'multi boot' ISO's with MKUSB?

[Israel]

Hi,
One other thing to add...
You can boot from an ISO file via Grub
It has been a while since I have done this, so some things may have 
changed... and NOT ALL DISTROS use casper as the root directory for the 
initrid/vmlinuz files, so look in the ISO for the file you need... for 
example Fedora is quite different

Some also need very specific boot parameters (like Arch)
So consult the ISO if you are using something besides *buntu, this is 
specifically targeted at *buntu use.

## this will be different on your computer, use the TAB completion
## some are something like (msdos1,1)
*set root=(*hd1,1*) *
## use tab completion here as well if you need
*set isofile=*"/path/to/FILENAME.iso"
## same as the root you set
*loopback loop*(hd1,1)*$isofile*
## the main thing is to include the path to the vmlinuz, and set the 
boot= that directory name... you might also need vmlinuz.efi if you are 
doing an efi boot

*linux (loop)/*casper/vmlinuz *boot=*casper
## some distros use different compression... so just check
*initrd (loop)/*casper/*initrd*.lz
*boot
*You**can also add a custom grub entry menu.

This could be done from a USB stick, technically, where you keep a bunch 
of ISO files, and make custom GRUB entries and boot each on separately


Again, I have not done this in a few years, (I have been using mkusb to 
overwwrite the same USB stick, like Nio) so things may have changed some.

The OBI does not work with iso files. But there are other tools, that 
can make multiboot USB drives, for example according to this link:


'One pendrive for all PC (Intel/AMD) computers - single-boot dual-boot 
multi-boot'


https://ubuntuforums.org/showthread.php?t=2259682

It works for Ubuntu and Ubuntu based distros, but you have to fix the 
menuentries in grub.cfg for the other linux distros.


There are also multiboot-usb, multisystem and YUMI


Would be nice to have 1 stick that can load:
32 bit
64 bit
pae
and eventually also the PPC


It is possible except PPC, because it has a different architecture, 
and needs different machine code.



And also to make a stick with all 32 or 64 bit *buntu's side by side.


You can make such a pendrive according to the link above or get one.

Some people like that, but I think it is better to consider pendrives 
as temporary devices.


I store iso files in my main computer's 'data' partition, and flash 
one of them to a pendrive, when I want to use it. If you want to bring 
many iso files in the pocket, you can have a second pendrive with iso 
files. It is a good idea to have fast USB 3 pendrives. They are faster 
in USB 2 ports too, because the flash memory hardware is often 
limiting the data transfer speed. See this link:


https://help.ubuntu.com/community/Installation/FromUSBStick#Prerequisites

I use mkusb (to wrap a safety belt around dd alias 'disk destroyer'), 
most of the time making simple live-only pendrives that are cloned 
from the iso files. Most iso files today are 'hybrid' iso files, which 
means that they work when cloned, so it is a very simple process.


It is a lot of work to keep a multiboot pendrive up to date, it can 
easily lag behind. It is somewhat complicated to keep the boot script 
(grub.cfg or a corresponding file for other bootloaders) up to date 
and working if you have several different distros.


There is also Ubuntu AIO at

http://linuxaio.net/


Specially now that 8GB is about the smallest stick size thats still
available in stores.

This would it make it less of a hassle to try a few distros.

I now have 4 Sticks in use for Lubuntu 16.04 64, 32, and alternate 64
and 32bit
that puts about 28GB doing nothing.

I have tried 2 multiboot options i could find but for some reason only
one of those partially works.

OBI looks like a good solution, but most distro's sit in a ISO.


Please try and find out which way you want to manage your iso files 
and boot drives :-)
