A few munin plugins installed with the base net-analyzer/munin assume ps is in /usr/bin/ps but really on Gentoo we've got it in /bin/ps
Just one that I can see. %% grep "usr/bin/ps" * ifx_concurrent_sessions_: my $pscmd = '/usr/bin/ps -p `/usr/bin/pgrep -P1 oninit -d,` -o ppid= -o args='; ifx_concurrent_sessions_: $pscmd = 'UNIX95= /usr/bin/ps -C oninit -o ppid= -o args='
Ah, the same exact thing is in 1.3.4 too. I'm not a user of this plugin and it isn't a regression. Sorry, I'm not interested in fixing it so I'm removing myself from CC.
Fixed in 1.4.5-r2
