Found a sweet spot for pthread support and the PR is updated, slightly reduces ifdefs and the pthread_test now passes. Still struggling on supporting TLS with musl libc. I would love to ask any opinions on the patch in any aspects since the changes are a bit large. |

build-rr.sh adds new -r option to switch what rump kernel is used: NetBSD is the default one and add Linux one for the alternative in this patch. Although there are several limitations (listed below) in this stage, this would be a first step toward supporting alternate rump kernel across different ones. Limitations: - no xen execution support (build should be fine) - no i486 build support - CXX is always false: CXX=false should be added to build linux rump kernel - no libz support - no cookfs (/rootfs) support - rumprun-packages needs more work: current test on travis is only build test and the executions might have various issues.

This is to ask your comment on an extension to support Linux kernel as a rump kernel.
(and the update of #65)
This commit requires the PR rumpkernel/buildrump.sh#78.
build-rr.sh adds new -r option to switch what rump kernel is used:
NetBSD is the default one and add Linux one for the alternative in this
patch.
Although there are several limitations (listed below) in this stage,
this would be a first step toward supporting alternate rump kernel
across different ones.
Limitations:
pthread is not properly implemented: tests are failed and usesTLS is still not workingTEST_LESS env for the minimum test
kernel
test and the executions might have various issues.
