does livemedia-creator only create live ISOs?

[duaneguthrie]

this maybe a dumb question, but does livemedia-creator only create live ISOs? i am trying to build a custom iso that will install linux and application onto the hard drive of a server.

the livemedia-creator is hardcoded to pick the "live" path in templates and they include lines like. replace @ROOT@ 'inst.stage2=hd:LABEL=${isolabel|udev}' ${BOOTDIR}/isolinux.cfg while the non-"live" path has content like. replace @ROOT@ 'inst.stage2=hd:LABEL=${isolabel|udev}' ${BOOTDIR}/isolinux.cfg

what parameters do you pass to just boot to CD/USB then complete install to hard drive of server?

You can use the live iso to install, but you need to run Anaconda in the live environment to do it, and it installs a copy of the live environment. If you want a traditional boot.iso style of install you need to modify the templates used by Lorax and build a new boot.iso like this: https://weldr.io/lorax/lorax.html#quickstart

ETA: I also have a blog post I wrote a while back that may help if that's the direction you want to go in - https://www.brianlane.com/post/creating-the-anaconda-bootiso-with-lorax/

I appreciate greatly the feedback and the tow links. (I did need to look up ETA. :) ). i took the Lorax template directory. copied the directory. i replaced the live templates and config with the non live versions. i am not testing this out to see how close it is to dvd iso.

if this does not work, i wall call lorax directly, as show in the first link.

copying the non-live to the live and using livemedia-creator had one problem with build (there is no prebuilt .discinfo (i can fix that). it failed on switch over with an empty /sysroot dir. only other thing i see is media.repo file is missing. i can create that. so it seems close! any advice feel free to share.

i mounted a dvd iso and my iso . they are now very similar.

fyi

my sysroot is still empty on switchover druing install. so i added trace to the x86.tmpl tmplate. it shows the install command is sometimes saving data at ${inroot}DEST.

so i am pursuing the Lorax rout. with a file based repo lorax -p "Rocky Linux" -v 9 -r 9 -s file:///iso-graft/rpm/Latest ./results/

there is no kickstart with Lorax, right? i need to edit or copy and modify the templates. right?

there is no "installpkggroup". right?

[duaneguthrie]

okay i am calling lorax and it is generating iso.

i am really stuck to kickstart and how to do the equivalent of skipx and first boot --disable.

okay i just found mkksiso in your tool box! does it make sense to generate boot.iso with lorax. then pass boot.iso, kickstart file, and file based repo to mkksiso?

[bcl]

Sorry for the delay, if that works for you then yes :) I'll look over this stuff in more detail next week.

[duaneguthrie]

My build now looks like this:

lorax --product="Rocky Linux" --version=${RELEASE} --release=${RELEASE} --source=file:///builddir/rpm/Latest --repo=/etc/dnf/dnf.conf --enablerepo=distribution --noverifyssl --rootfs-size 5 ./results/

mkksiso --ks ${KICKSTART_FILE} --add /builddir/rpm/Latest --debug /results/images/boot.iso /results/images/test.iso

my understanding is that --add /builddir/rpm/Latest \ will build file file based repo into the image. where should my url and repo commands expect it to be?

url --noverifyssl --url=file:///iso-graft/rpm/Latest repo --name=distribution --baseurl=file:///iso-graft/rpm/Latest

[bcl]

https://weldr.io/lorax/mkksiso.html#adding-package-repos-to-a-boot-iso

So it should be: file:///run/install/repo/Latest/

The --add copies the directory to the root of the iso and the iso is mounted on /run/install/repo/

You can also boot the iso in text mode (pass inst.text on the kernel cmdline in grub) and poke around with the shell on tmux pane 2.

[duaneguthrie]

thanks, trying that

@duaneguthrie Did you get this working?
