Just wanted to say that I think emerge should be filtering that variable out, along with some others that are probably a bit more contentious.
It's completely useless information-wise, and certainly shouldn't be used by make et al (or something is wrong.) |

Well the user has EMERGE_DEFAULT_OPTS="-va" and did not disable it for the that info output (I did that mistake once for a bug report... oopsies!), so yes, Portage is definitely being verbose there but at least it's on purpose. ^^

It's not the verbosity, it's that emerge already filters out some variables, and this one is always way too big, and functionally useless. It just clogs up the environment bz2 (and incidentally makes it much more awkward to look at in some editors.)
Still I should just mention it to zac next time I'm bugging him about portage's behaviour ;)
Sorry for noise. |

When you do, you might want to have a ready suggestion:
I am using since years the following "emerge" command (ordered in $PATH before emerge) which cleans up my environment before calling emerge, and which even explicitly passes through some variables which you might want to set temporarily in the environment.
I am sorry, we get now again a very wide output since I have implemented the thing with a huge "case":
| Code: | #!/bin/sh
PATH='/usr/sbin:/usr/bin:/sbin:/bin'
printf '%s\n' "USER=${USER}"
# cd two times to erase OLDPWD
cd
cd /
IFS='
'
unset k
unset t
unset u
for i in `env|sort`
do j=${i%%=*}
case ${j} in
