Well. I stumbled up on yet another video of retro PC runs Gentoo.
It's a Pentium, so not that extreme as 486. :P

Dependency calculations take... quite long. I guess python is a huge overhead.

I recall my SC520 (Am486 class, 133MHz SOC) taking almost 2 minutes to run 'emerge' with no arguments.

I love how this part takes like five minutes

I wonder what would be difference in bootup time between openrc and systemd.

I wonder if systemd requires some CPU instructions not found from Pentium (1).

I don't think systemd requires i686 except for any glibc-related limitations like cmpxchg. Oh... forgot about polkit, but that was solved recently.

You know, I do have that K6-233 running Gentoo, minus no GUI due to it not having graphics drivers. The K6-233 is Socket 7 and I think I have a P5 chip somewhere...

If systemd were ported to Rust, it could easily gain an i686-dependency. ;)

main reason for /not/ upgrading Gentoo on my K6-233 is that I'm still using a kernel that supports ISA on that machine and uses ISA cards (it uses an ISA network card, though it does have PCI slots)...

Why I had the impression that Linux never did support ISA? I though a sec about it and concluded of course there is/was support.
Aren't some sensors on internal ISA bus?

ISA is still "sort of" supported in terms of it still is the basis for LPC.

However all of the traditional ISA drivers for network cards, SCSI cards, etc. were deleted from the kernel and thus unmaintained even if one was to pull them back out of git. So they are no longer supported.

Incidentally watching the video, I thought I saw AGP cards... I didn't think there were AGP cards until P2's? Well, maybe there were Super7 AGP boards, but that's not well matched for a P5-133 ... then again my Socket7 board likewise supports SDRAM, though at 256MB SDRAM, it does not cache any of it.
