Installing Gentoo Via Arch/CachyOS. issue /run/shm

"When using non-Gentoo installation media, this might not be sufficient. Some distributions make /dev/shm a symbolic link to /run/shm/ which, after the chroot, becomes invalid. Making /dev/shm/ a proper tmpfs mount up front can fix this: " is arch/cachyos one of the distributions that do NOT make this symbolic link? i cant seem to find /run/shm so this leads me to think that it doesnt but I wanna be sure. This will be my second time installing gentoo and Im doing it properly and going deep into the nitty gritty of everything where as last time i did a quick speedrun with barely any customisation so pretty much like redcore but harder. just followed a guide by a youtuber called denshi. He does it on linux mint but I already had a cachyos iso so i just rolled with that.

The easiest thing to do is check when you're at that step.

Looking at the cachyos cli installer, it's a nearly 1GB ISO. For a cli installer, that seems really, really large.

It's also 2+ years old (sourceforge, which cachyos lists as a source)

i should have mentioned im using cachyos as a livegui install method instead of mint or something else...

may i ask how and what i am meant to check at that which step as I am at that point in the guide where I am made aware of this situation... arch and cachyos dont seem to have /run/shm and so can I just forget about it in this case or do is there something else i ought to do.... I tried doing as the guide said anyway in the warning and i get another error, so this leads me to believe that i dont have to deal with that symbolic link stuff.
Thanks again people!

I don't recall the specific point in the guide where it mentions that, but I presume you have to be booted to the cachyos livegui to be there, no?

Its under the page installing the base system https://wiki.gentoo.org/wiki/Handbook:AMD64/Installation/Base and under the chapter? Chrooting. the first red box. I have gotten to that stage in the cachyos live gui and have tried running what is said in the guide as i have linked above and i just get the error that no such directory exists...
I am booted from the cachyos livegui, I tried the livegui by gentoo itself but i couldnt actually get the live gui, only the gentoo@livecd terminal interface.
Can I just skip this minor point as it seems i dont even have the directory to begin with? or...

At this point you would not yet have "entered" the chroot which is the next step, correct?

If I understand what you're indicating, the cachyos livegui does not have a /dev/shm entry at all, correct? What is the output of ls -ld /dev/shm ?

If it indicates "No such file or directory" then I would create it as per the instructions in the Warning block which include "mount ..." followed by "chmod ...".

It seems to me the guide expects it to exist, and to exist in a certain way.

See your other thread, I've pointed you to the correct reported working live gui iso. Last night I just glanced over the relevant thread and picked up the problematic link, instead of the working one.
