User Mode Linux is still around and works well. I use it when I need a "fakeroot" without any special privileges on the host. https://rkeene.org/viewer/tmp/fa

- mikepurvis 5y agoThanks for the poke on this. I had looked briefly and become frustrated that many of the instructions I found assumed you were a kernel dev and started with compiling everything from source— the Debian-supplied UML binaries seem to work well for my needs though, and do indeed allow doing basic stuff like mounting a disk image so you can run install-grub on it.
- rkeene2 5y agoHmm, building UML from source is really easy. Here [0] is my process for doing it, as a Makefile. The actual compile step is just one line (line 32): $(MAKE) -C linux-$(KERNEL_VERSION) ARCH=um linux The rest of it sets up the configuration how I want and compiles other dependencies (like slirp) or is for maintenance, like cleaning up, or downloading. This is a rather old version -- newer versions check the checksum and use my HashCache system. [0] https://rkeene.org/viewer/tmp/uml.Makefile.htm https://rkeene.org/viewer/tmp/uml.Makefile.htm
