Here is my two cent's on Clarity 's post - https://forum.puppylinux.com/viewtopic.php?p=12477#p12477 and foxpup 's comment: What is wrong with 32bit anyway? What is wrong with an old puter?

foxpup wrote By the way, I do consider legacy boot superior to EFI, for personal computers anyway. The problem with legacy boot is the old BIOS cannot verify that the boot loader is secure. Although, not relevant for Puppy some other distros now verify all software - boot loader, kernel, kernel mod...

It is clear to me the design of EFI booting is meant to support booting from both GPT and MBR disk. There are m...

I have a MBR formatted disk (gparted -> View -> Device Information -> Partition table: msdos). I can do a EFI boot from this partition.

Actually, this supports my position not bigpup's.

rcrsn51 It cannot be doing compatibility CSM BIOS booting. The flash drive was a data only drive, i.e., its MBR only has a partition table and was never patched with boot code. Further, since I only do UEFI booting, my Puppy partitions do not have the MBR boot loader ldlinux.sys. Even if it did the...

Bigpup's instructions are excellent.
Everything is prepared for your convenience already and tested many times.
You cannot do better yourself.

This is not true. For a UEFI only boot partition something much simpler will work. Think about it for a few minutes.

bigphil wrote Most computers bios always expect to find the boot loader on the first partition and flagging the partition boot, makes sure they look on that partition and only it. If you are using this USB to boot a computer with UEFI. The first partition on the drive will be considered the boot pa...

mikewalsh wrote I'm genuinely curious, I admit.....and out of that same curiosity, I'm now wondering; how are you selecting the partition to boot from? You must be using a boot 'menu' of some sort.....or are you selecting these through the "one-time boot menu" thingy most machines are equ...

It occurred to me that the "run-as-spot" script can be hacked to also run seamonkey portably. Using a bit of code from mikewalsh's portable Iron browser I wrote the following: #!/bin/ash # wrapper to run seamonkey portably as spot (when currently running as root) # should be located in the...

Uten wrote As for the root is not a secure thing. I love my puppy because I can use my computer. It is not locked down. I suppose you could hack it, but there is a catch. When I reboot, your hack is gone! So I always boot a secure fresh version for banking and such. Are you booting from read-only m...

bigpup , Uten your suggestion to use "run-as-spot app [arguments]" works - thank-you very much. I did not know about "run-as-spot". Since, Puppy is derived from Ubuntu, I have been using the Ubuntu documentation as my Puppy documentation. Although, this in general works quite we...

ndujoe1 In my opinion Puppy Linux compared to other systems is architecturally very weak with respect to security. Other systems use a multi-layered defense against infection. Specifically, technologies such as DAC, MAC (SELinux, AppArmor, seccomp) strongly limit the damage an infecting agent can d...

mikeslr I fixed my post as you suggested. if this was a dynamic dependency problem then would not SeaMonkey also fail to run using user root? SeaMonkey runs quite well using user root but I think running browsers as user root is unsafe so I want to run it as user spot. # ldd seamonkey linux-gate.so...

PipzDex Thank-you for your help. Although I did not install your attached .pet file as my workaround works well enough for me. I did analyze it to try and find out what "Precise Light 5.7.2" might be doing wrong. I diffed the glipper_shell scripts of "Precise Light 5.7.2" and yo...

On a USB flash drive, I have installed "Precise Light" and "BionicPup64" to two separate GPT partitions, '(hd0,msdos3)' and '(hd0,msdos1)', respectively. Each installation has its own "/EFI/boot/bootx64.efi" and "/grub.cfg". However, on the UEFI boot no matter...

Since the forger of an iso file can create a forgery that matches the original MD5 what is needed is a digital signature. However, Puppy iso files are not digitally signed, (I really don't understand why they are not distributed that way. AFAIK all Microsoft distributed software is digitally signed ...
