Ok, I thought I'd share this with everyone, since it made things much faster for me.
First, note that many modern Linux distributions do not build or bundle the efs filesystem anymore. I am running CentOS 7 on my main box, and followed the instructions at https://wiki.centos.org/HowTos/I_need_the_Kernel_Source and then https://wiki.centos.org/HowTos/BuildingKernelModules to get a working efs.ko, which I put into place the normal way. Setting EXTRAVERSIONS in the kernel Makefile was required for my build; YMMV. I am an old hack at building RPM's, but I haven't built a kmod-efs as yet.
Ok, so once a properly versioned efs.ko was in the correct place for the installed kernel to find it, the following commands, as root, will load it:
Now, I had previously imaged my IRIX distribution disks, and had all of them in one directory, named with a '.image' extension. I then created a mount point, mnt:
Here's the one-liner that, in a little over two minutes, exploded all the files out of the 22 disk images I have:
(yeah, I know --progress is just eye candy..... but this is an IRIX forum, no?
) and here's the resulting directories with their sizes:
I hope that helps someone.
Now, to set up a DINA VM on my CentOS 7 box using KVM......
