`sed' is complaining about a bad substitution flag. Here's the expected behavior:
$ awk '/sed/ && /UNAME/ {print NR ": " $0}' /usr/local/share/poudriere/common.sh
2860: sed -i "" -e "s/,UNAME_r.*:/:/ ; s/:\(setenv.*\):/:\1${login_env}:/" \
$ cat testfile
:setenv=MAIL=/var/mail/$,BLOCKSIZE=K,UNAME_r=10.4-STABLE,UNAME_v=FreeBSD 10.4-STABLE #0:\
$ sed -e "s/,UNAME_r.*:/:/ ; s/:\(setenv.*\):/:\1${login_env}:/" testfile
:setenv=MAIL=/var/mail/$,BLOCKSIZE=K:\
Try running the sed command by hand one piece at a time to troubleshoot what's breaking.
$ sed "s//,UNAME_r.*:/:/" ${mnt}/etc/login.conf
$ sed "s/:\(setenv.*\):/:\1${login_env}:/" ${mnt}/etc/login.conf
$ echo $login_env
