Subject: build.sh: Use 'id -u -n' instead of 'whoami' for POSIX compatibility
X-Git-Url: http://git.tremily.us/?p=dockerfile.git;a=commitdiff_plain;h=a85052ce3f9ea8c258aa3ae832a9d1bc18c597c1

build.sh: Use 'id -u -n' instead of 'whoami' for POSIX compatibility

'whoami' isn't in the POSIX spec, but 'id -u -n' is in POSIX and does
the same thing [2].
