# - 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....
