Ah my mistake. I'm just generally curious about what distros use an alternative to systemd (not that I have any issues with systemd myself but I like variety).

So I googled what init system Slackware uses and read this page.

http://slackware.com/config/init.php (no https)

They mention several scripts on that page and that's why I thought they use scripts.

But I haven't actually used the Slackware yet. Suppose I should though since I'm interested.

I was reading about Slackware today and it seems their init system still uses system V and lots of scripts.

So I'd definitely recommend that OS to anyone curious about the old style of init system.

I tried both. They have the exact same questions.

However the one op posted respects the "I don't want systemd" request. And I personally prefer to get multiple answers.

But the mobile webdesign on ops posted link was not great. So it's a wash for me.

I've definitely made similar errors dual booting. I don't know what your budget or hardware is like but if you can fit a second hard drive in your computer it is very worthwhile for distro hopping.

The second hard drive will let you install whatever boot loader the USB installer wants to install without overwriting the bootloader on the first hard drive.

Modern grub is pretty magical and should detect both OSs either way.

But yeah that's why there are so many warnings in every Linux distro about installing grub. You do not want to mess with a currently working bootloader.

This is mostly because the bootloader needs to be in a very specific location on the hard drive and so you can't just install it anywhere. Which means you have to overwrite the old boot loader if you choose to install a new one.

I'm gonna try these out. The history search one is cool.

Plus I had no idea you could use args in an alias. I had to make a function in my .bashc the last time I needed args.

Edit: For anyone reading this in the future ECMA-119 is freely distributable and seems to conform to ISO 9660. ECMA also have versions of some of the specs referenced by ISO 9660. (ECMA-6, ECMA-35, ECMA-43)

Will do. I was gonna start by reading ISO 9660 and I found out it costs 200 dollars from standards.iso.org. Which is a shame because there's a bunch of other ISO standards referenced in 9660 which would cost even more money to read. I always heard people reference these standards but I had no idea they were so inaccessible to regular users. But I think I found some kind of annotated copy of the spec to read,

Thanks. I see the word boot is referenced 200 times on the related manual page. So I suspect a thorough read through of that page will help me.

Alright thanks. Well if you know of any good resources for xorriso particularly with the -b (boot) flag I'd like to read them.

Google has been mostly serving me 15 year old SO posts that aren't relevant to modern Linux anymore.

I found Gentoo more helpful than LFS because with LFS you compile about 80 packages from source one at a time but you don't learn too much about the packages.

LFS gave me much more awareness of what packages actually come with a Linux install but Gentoo taught me more about configuring and booting a Linux system.

Although I'd definitely recommend both to anyone wanting to learn. I'd do Gentoo first then LFS.

Edit: LFS is also a masterclass in cross compiling so if that's something you're curious about LFS is the way to go.

So eggs is great for Debian with my Gnome stuff.

As for xorriso I have a LFS dir that very much resembles a Linux root dir (without a DE or any distro specific software) and I can chroot into it mounting /dev, /sys, /run, /proc from my host system.

I would like to compress that LFS dir into an iso combined with a boot loader.

That LFS dir is on a separate partition and does have a boot loader installed on that partition's hard drive. But I'd rather boot it in a virtual machine and I didn't want to give the vm raw hard drive access.

I hope that helps but I'm happy to answer more questions.

Booting into a live CD isn't a hard requirement because I can probably just use eggs after I get it to boot in a vm.

Edit: also thanks for the insight about xorriso I had real trouble finding much info about the differences between the three.

Edit 2: I'm going to run LFS on the exact same hardware it compiled on so I can probably use grub installed on my host system.

That said I did try using grub-mkimage on my host system and when passing that iso into mkisofs -b I still couldn't get a boot. (No bootable medium found.)

Going to try the penguins-eggs method you posted. I would love to be able to turn a virtual box environment into an installable medium to make my own version of debian with all my gnome tweaks.

I would also love a solution that doesn't require booting into the OS first. So that I can take a root dir and turn it into a bootable iso. I tried a bunch of old tutorials for making a boot.iso and linking it into mkisofs with -b but it never worked.

I am willing to learn/use any free tooling. Not picky at all.
