[The fix](https://github.com/golang/go/issues/17986) for the small buglet addressed by `misc-cgo-testcshared.patch` has been merged into the tree a while back. I was surprised to see that it wasn't in 1.7.5 and did a bit of digging. It is *has not* been merged into the 1.7 branch but it *has* been merged into 1.8 (and therefor the patch will no longer be necessary). Figured I'd document my digging for the next person to come along.

# - vanilla CentOS 7, and possibly other systems, fail a test:
|

# TestCloneNEWUSERAndRemapRootDisableSetgroups
|
|
#
|
|
# The Fix, discussed here: https://github.com/golang/go/issues/16283
|
|
# is to enable "user_namespace".
|
|
#
|
|
# On a Digital Ocean image, this can be achieved by updating
|
|
# `/etc/default/grub` so that the `GRUB_CMDLINE_LINUX` variable
|
|
# includes `user_namespace.enable=1`, re-cooking the grub
|
|
# configuration with `sudo grub2-mkconfig -o /boot/grub2/grub.cfg`,
|
|
# and then rebooting.
|
|
#
|
|
# - on CentOS 7 systems (and possibly others) you need to have the
|
|
# glibc package installed or various static cgo tests fail.
|
|
#
|
|
# - When building on a *large* machine (144 cores, 1.5TB RAM) I need
|
|
# to run `ulimit -u 8192` to bump up the max number of user processes.
|
|
# Failure to do so results in an explosion in one of the tests and an
|
|
# epic stack trace....
