Live slack w/persistence ... hack

BW-userx · 05-04-2019, 05:52 PM

is there a way to get slack live on a SD Card and not a usb stick with persistence. I've been hacking on iso2usb but not getting too far.

it does create all 3 partitions, it just seems to not be able to format them so it fails?

Code:

userx@slack.current.edo:/media/data1/liveslak
$ sudo ./iso2usb.sh -i slackware64-live-current.iso -o /dev/mmcblk0 -f -c 70%
#
# We are going to format this device (erase all data) - '/dev/mmcblk0':

I just hacked in a hard code to sd card

Code:

# Either provide a block device, or else scan for a block device:
if [ -z "$TARGET" ]; then
  if [ $SCAN -eq 1 ]; then
    echo "-- Waiting  ${SCANWAIT} seconds for a USB stick to be inserted..."
	TARGET=/dev/mmcblk0
  #  TARGET=$(scan_devices)
    if [ -z "$TARGET" ]; then
      echo "*** No new USB device detected during $SCANWAIT seconds scan."
      exit 1
    else
     TARGET=/dev/mmcblk0
   #   TARGET="/dev/${TARGET}"
    fi
  else
    echo "*** You must specify the Live USB devicename (option '-o')!"
    exit 1

In case of a SD card (eMMC devices), the partitions names are like mmcblk0p1 not mmcbkl01.

elcore · 05-05-2019, 05:44 AM

Had a mmc install once that worked ok, until power management had cut off power to mmc reader (ricoh on acer) corrupting the partition.
I've given up at that point, maybe you will have better luck.

I’m going to take a closer look at that and try to figure out them functions as soon as I get a chance. Right now I’m reading this from my phone.

Try the modified script which I just uploaded. It should work with your SD card now.

Suggestion: use lsblk instead of fdisk as well to find the partitions names, line 630 would become:

Code:

TARGETP1=$(lsblk -l -o name,type|grep $(echo $TARGET|sed s,/dev/,,)|grep part|cut -d' ' -f1|grep 1$)

Just my 0.02 €

changed that line to yours, and echo'ed it too just to see what it is suppose to have. it is blank???

linus72 · 05-05-2019, 08:17 PM

hack it manually bro and see if it works...thats what I do

Anyway, before we go further please provide the full output of this command, typed with the SD card plugged in:

Code:

lsblk -l -o vendor,model,name,size,type,fstype,pkname,mountpoint,rm

I understand from this that the SD card was properly written using my modified script.
But when you boot it next, the Live init process fails to find the SD card. I guess I will have to enhance the liveinit.tpl file as well to add support for SD cards. I'll have a look.

Hmmm looking at the first picture, it says "Live media found at /dev/sda1" which will in no way be your SD card. Did you perhaps have a CDROM inserted in the drive with a Slackware Live ISO copied onto it? Because when liveslak encounters multiple media containing Slackware Live, it will just pick the first one in the list and that will not always be the correct one.

The second picture has kernel symbol errors. Did you add a custom kernel and/or modules to that ISO image?

that is what I was wondering why is it looking at sda1.
why is it is showing anything about trying to get to sda1?

With you mentioning a CDROM, that has to be (maybe) for the HP EliteBook 8460p that has SATA hdd, and a combo DVD / secondary hdd setup, where I have a secondary hdd in lue of the DVD that use to be in it. (perhaps).

I have the directories that have all of the staging and liveslck on that hdd. Because my root partition on this Laptop is at no room, it kept going to zero space left, to the point it is now screwed up when I did an system update and I am now getting file too short errors when it tries to use any lib.so and I can no longer startx having given it room again. but that is another issue I got a deal with on that laptop.

HP EliteBook 8460p

32GB ssd and 250GB ssd

I got two distros installed on a 32GB ssd, VOID Linux and Slack current, and I now it is running out of space on both during updates. so I am sitting here wondering what or which one to remove. Slack current is taking up more than 15GB. which this is totally side tracking this SD Card issue.
------------------

the other Laptop is a HP EliteBook 840 g2 No CD/DVD and as far as I see only gives me SD Card boot option when I use the UEFI and legacy combo or pure UEFI boot option in BIOS. SATA hdd, and M.2 PCIe Solid State Drive. that M.2 is seen as /dev/sdb and that is where I have to direct it to install grub and boot from sdb, and not sda. That (sda) is being used as a data storage drive.

Just trying to boot that in Legacy mode the BIOS removes the option to use the SD Card off the list in BIOS.

I probably gave you more info then needed/wanted, so while you're picking your brain on that, I'll be trying to figure out what to do with this no space left hp 8460p laptop, and dealing with that, something I did not have on my list of things to do, before I can get back to the SD Card thing.

I just did yours because the other messed up so I did it to see what it would do, then posted back my results. as I am now dealing with slack no room screwed up update on the hp 8460p right now, I'll get back to your request when I am done with that. sorry I cannot post that put someone on hold music here. or I'd play you something nice to listen to.

Or as I am on the usb slack stick right now on the hp 8460p to redo my partitions so I can fix this dual distro no room left situation. so...
