for those that want to use the slackware 15 live from a usb its here : https://slackware.nl/slackware-live/slackware64-15.0-live/ i believe that once running live you can evoke an install script from the live os setup2hd i believe. Currently downloading live slackware 15 iso . Will edit if thats wrong
I need to check which mirrors should be used current or stable ; not exactly sure I think current freezes for a while , should be interesting if anybody from slackbuilds.org contacts me for the one I maintain
Desktop I used plasma x11 gdisk, cfdisk are there by default and I noted a wacom tablet help finder
update: i'm on live 15 now - had problems with slpkg - i think the devis behind don't bother with it.
update I forgot that just using "dd" isn't going to give and persistence and thus , that was the reason for failure with slpkg
I haven't installed slackware15 to any PC, so I had to use the dd version of slackware 15 live and use Alien Bob's iso2usb.sh script and use that to format another usb with thr live iso. This time after installing a few packages got slpkg working. See image where i searched for nano
