Installing Linux on the mainframe is too hard you say?
It’s not so bad. All you do it get the files you need (there’s only three files you need from debian’s site). Create two fake DASD files and startup the emulator.
Then, we just turn on the mainframe
and tell it to IPL 000c (which is the card reader, which the startup files for Debian/390 is in)
To which it boots a normal-ish looking debian install
you basically just setup the networking and then tell it a password to connect and finish the install
it looks no different than a normal install
where you select the harddrives and format them
install the packages you wanted
and setup the default user
Then you reboot, and IPL the DASD you installed this shit on and…
anyway, there, Linux running on z/OS emulator. Maybe I’ll fuck around with this later
Any other requests? This was actually a nice challenge. I guess I could try and setup VM or DOS…
