The man make.conf says about PORTAGE_IONICE_COMMAND:
Defaults to "ionice -c 3 -p \${PID}".
But when i don't set PORTAGE_IONICE_COMMAND in make.conf and look to an
subprocess of emerge i see:
# ionice -p25908
none: prio 4
lookin on emerge shows me:
# ionice -p8875
none: prio 0
but the scheduler should be set to idle. this works when i set
PORTAGE_IONICE_COMMAND="ionice -c 3 -p \${PID}" in make.conf
Reproducible: Always
Steps to Reproduce:
1. Unset PORTAGE_IONICE_COMMAND in make.conf
2. Check process priority whit: ionice -pPID
Actual Results:
# ionice -p25908
none: prio 4
Expected Results:
# ionice -p25908
idle

Thanks, the man page is fixed in svn r12003 to indicate that the variable is
unset by default.
Initially we had it enabled by default, but not anymore because it's not
supported by some kernels, and some kernels support it with any user while
other kernels require root privileges.
