Re: [Libguestfs] compile libguestfs 1.19.35



[The context for libvirt users is how to let people do
'make install' without having conflicts with installed copies
of packages.]

I'm not sure how special libvirt & qemu are.  You could try installing
to a local prefix (I sometimes use "./configure --prefix=$HOME/gnu").

Then you have to sort out the environment variables that need setting.

I don't think libvirt or libguestfs or qemu document what environment
variables should be set to run an internally consistent local copy
of the entire libvirt/KVM stack from your home directory.
libguestfs has the "./run" script which can be modified.

Anyone got any thoughts?  I think it is a genuine concern.
