Puppy Linux Discussion Forum

For those who haven't been following recent Limine discussion on the forum, Limine is a very simple bootloader, for both legacy-BIOS and UEFI computers. With either msdos partition table or gpt boot drive.

Its simplicity and capability make it an attractive alternative to others such as grub2.

I have started work on a "Limine Installer".

This is intended, eventually, to be an installer for the Limine bootloader, when installed to present a menu for booting any Linux installation, including Puppy, Puppy derivatives, EasyOS, Fatdog, etc., and Windows.

To get started, I have knocked together a script that detects what is installed on the computer. I welcome anyone with some shell scripting ability to test the script 'find-installations' and see if it detects all Linux and Windows installations on your computer, and if not, edit the script so that it does detect everything.

Run it from a terminal, it outputs some progress. The results that it finds are in folder /tmp/limine-installer

Script attached, with a false ".gz", and of course you will have to set its executable flags.

EDIT JULY 7:
The script is updated, see attached.
It requires 'lsblk' utility, in the 'util-linux' package.

I was on FatDog when I saw this. so tried it there first. I have Win 7 on the first partition and EasyOS, FatDog, FossaPup, studio1337, and ClearOS (frugal install using wiak's weedogit.sh method) on the next partition.
After running the script I just get:

Found Puppy
Found EasyOS

On EasyOS (just did the update to 4.2.3) I get:

# ./find-installations 
ls: cannot access '/dev/disk/by-partuuid/*': No such file or directory
ls: cannot access '/dev/disk/by-partuuid/*': No such file or directory
Found Puppy

ls: cannot access '/dev/disk/by-partuuid/*': No such file or directory
ls: cannot access '/dev/disk/by-partuuid/*': No such file or directory

The tmp files are accurate for the EasyOS and Fossapup installations, and show the NTFS partition has been detected, but not W7.
I see the script just looks for bootmgfw.efi but this is not present. Not sure what the best marker for W7 would be.

Oh, that's an awkward situation on Fatdog. It has the busybox 'blkid' utility, which does not report PARTUUID -- the full 'blkid' from 'util-linux' is required.
The script detects that you only have the busybox 'blkid', so falls back to reading /dev/disk/by-partuuid. However, it seems that the Fatdog kernel is not configured to display that information. On most Linux distributions, the kernel is configured to display that info -- I don't recall what config settings are required.

@jamesbond
Looks like need to contact the Fatdog devs and ask them to either use the full 'blkid' or change the kernel config, or come up with some other way to read the gpt partition-uuid.

James,
If you read this, notice in the script, I left the fatdog-specific detection empty.

Keef,
I seem to recall, you also do some Fatdog development?

EDIT:
I just remembered, it is not a kernel config, /dev/disk is populated by udev rules

Voidpup is a frugal install?
Does it have 'initrd.gz' and 'puppy*.sfs'?

How deep are the easy frugals installed?
The script only searches 2-deep, that is, for example, /easyos/dunfell
I could change it to search 3-deep.

EDIT:
Also, only finds Easy frugal with everything in the working partition, working dir.

Running the script from debian dog bullseye..

This is partly correct however it does not count the dog i`m booting from which has vmlinuz1 and initrd1.xz in /bullseye/live in the same partition with the other puppies. I have 3 puppiues and d-dog in there. /etc/os-release is a symlink to /usr/lib/os-release.
It also missed two linux installs. One (debian) has initrd.img-5.9.1-rt20avl1 and vmlinuz-5.9.1-rt20avl1. The other (manjaro) has initramfs-5.18-rt-x86_64.img and vmlinuz-5.18-rt-x86_64. In both cases /etc/os-release is also a symlink to /usr/lib/os-release.

sda2 there is a frugal voidpup 1 level down. yes,'initrd.gz' and 'puppy*.sfs' there are no easy frugals, in / or one or two levels down

if I also tether a ssd on a usb cable, and mount sdb2, I show the same results as above.
sdb3 has, at one level down in individual subfolders for each frugal,
2 voidpup

Do the *dogs all have that naming, 'vmlinuz1' and 'initrd1.xz'?
if so, why the "1"? Is it to distinguish from Puppy installs?

For the debian and manjaro installs, are those initrd* and vmlinuz* files in /boot folder in the installation partition?
That is my understanding, that /boot is the standard place for those files.

Alfons discovered a bug. The Windows recovery partition has a label with a space character, which breaks the line that parses output of 'blkid'. Fixed. Will update the script soon.

Note that the script ignores usb drives.

There is a post above about failure to find the PARTUUID of a partition.

Tricky situation with pups that only have the busybox 'blkid' and don't have /dev/disk populated.
I have implemented a fallback, to use the 'gdisk' utility:

 #get f.s., label, uuid, and partuuid...
 LABEL=''; UUID=''; TYPE=''; PARTUUID=''
 #20220706 there is a Microsoft label with a space...
 #aBLKID="$(blkid /dev/${aDEV} | tr ' ' '\n'| grep -E '^LABEL=|^UUID=|^TYPE=|^PARTUUID=')"
 aBLKID="$(blkid /dev/${aDEV} | sed -e 's%LABEL%\nLABEL%' -e 's%UUID%\nUUID%' -e 's%TYPE%\nTYPE%' -e 's%PARTUUID%\nPARTUUID%' | sed '/^\//d')"
 blkid -V | grep -q 'util\-linux'
 if [ $? -ne 0 ];then
  #the full blkid from util-linux pkg displays the partuuid, busybox blkid doesn't...
  if [ -e /dev/disk/by-partuuid ];then
   #/dev/disk is populated by udev rules.
   PARTUUID="$(ls -l /dev/disk/by-partuuid/* 2>/dev/null | grep "/${aDEV}$" | grep -o 'by\-partuuid/[^ ]*' | cut -f 2 -d '/')"
  else
   #getting desparate. some pups don't have /dev/disk
   if which gdisk >/dev/null ;then
    aNUM="${aDEV##*[a-z]}" #extract partition number.
    GPARTINFO="$(echo -e "i\n${aNUM}\nq\n" | gdisk /dev/${aDRV} 2>/dev/null)"
    PARTUUID="$(echo "$GPARTINFO" | grep '^Partition unique GUID' | rev | cut -f 1 -d ' ' | rev | tr '[A-Z]' '[a-z]')"
   fi
  fi
 fi

If a pup doesn't have 'gdisk', that is unfortunate. But then, you should be running a reasonably modern pup when run the Limine Installer, and it should have gdisk. Maybe not builtin though.

That is my understanding, that /boot is the standard place for those files.

I have mostly used bullseye but I checked on another machine a buster-dog which has the same naming as bullseye and an unbuntu-dog install and found the "1" on the initrd but not the vmlinuz. Seems consistent but I can't comment on the reasoning..

Yes, both linux installs have the init* and vmlinuz* files in /boot of their respective partitions.

On this other laptop the script returns to prompt, without errors or output. This machine has 2 dogs, fatdog and puppy in one partition and Arch in another.

Thanks so much for your work on this!

I have almost completely rewritten the script, using 'lsblk', which is in the 'util-linux' package.
No longer need fdisk, blkid, nor gdisk.

Will upload the new script soon.

In both cases /etc/os-release is also a symlink to /usr/lib/os-release.

@puddlemoon
Thanks very much for the info.

Can you tell me, is /etc/os-release a relative link, or an absolute-path link to /usr/lib/os-release

In Puppy|Easy, with ROX, you mouse-over /etc/os-release, and if it shows link starting with "../" then it is relative.

@BarryK
The links are relative with the leading "../"

I have only one install of jackalpup but I have a puppylivecdbuild still populated in /mnt/home so I'm guessing it found that. I also have a studio 1337 frugal but the main sfs has been renamed to exclude "puppy" (for business purposes I'm guessing). So not being a puppy*.sfs perhaps took on the nearest?

The limine-installer PET will have /usr/local/limine-installer folder, with scripts inside. So far:

depend-checks
find-installations
generate-menu-entry
limine-installer

What it is doing so far, is 'limine-installer' calls 'find-installations', then brings up a gui with checkboxes, so you choose which of the found OSs you want to create Limine menu entries for, then calls 'generate-menu-entry' for the ticked checkboxes, then brings up the result in a text editor.

So, no actual install, hope to get onto that sometime. Anyway, the current status, having the entries created, that you can just insert into 'limine.cfg' is quite useful.

I have set aside a PC just for installing different Linux distros, so I can see exactly what their layout is. Have started with Debian, downloaded the "netinstall" iso from here:

https://cdimage.debian.org/cdimage/unof ... 64/iso-cd/

...in retrospect, should have just downloaded a full CD/DVD iso, as this thing has been downloading packages for the last hour, and the progress bar hasn't even reached halfway.

I have another request. I want to detect whether the computer has UEFI-BIOS or legacy-BIOS firmware.
I found that running this:

# dmidecode --type bios
 ...
  UEFI is supported

But, do all UEFI-BIOS firmware return that string?
Would you mind running that command on your PC with UEFI-firmware to confirm?

Note, all x86 computers manufactured from 2012 have UEFI-firmware.

For me it does return that string on a Asus SonicMaster laptop.

I do get that in the list of strings produced when that command run on HP Probook G8 430

lenovo X-250 includes the string

lenovo T-420 does not in spite of both the following settings in bios setup chosen ...

UEFI/Legacy Boot [ BOTH]
UEFI/Legacy Boot Priority [UEFI First]

CONFIRMED for Dell Latitude E7250 with BIOS dated 2020. As i boot up some of my lesser used computers, I'll report back my findings.

UEFI is supported is returned on my 2021 ASUS ZenBook laptop

Thanks for the feedback!
