Hi,
is there a way to change the MAKEOPTS setting on a running
emerge? I am using "-j 5 -l 4" whilst emerging gcc-9.3 but its
creating too much pressure on memory. I expect the emerge to take
many more hours but complete eventually - but reducing it to "-j2"
will help other operations whilst not losing whats already been
completed (this is an old atom N330 with 4G ram and is my
gateway/router/firewall/snort/... and the overload is starting to
affect the network throughput significantly).

ionice is in sys-apps/util-linux, so it's probably already installed.
schedtool though is in sys-process/schedtool and it might not be
installed.

The nice level can also be adjusted with `renice` from
sys-apps/util-linux:
renice -n 19 -p pid
Yep, forgot about that. However, I have observed that the nice level
doesn't have much impact. But setting a process to SCHED_IDLEPRIO
(schedtool -D) and nice level 19 (schedtool -n 19) has a huge impact.
