Subject: package management with yum: handling stuck processes

Hello folks,
I've discovered recently that yum package manager under Cfengine occasionally
becomes stuck, so that subsequential invocations of cf-agent try to run "yum
list installed" over and over again, waiting for the lock from the stalled
process. By unknown reason, Cfengine does not terminate stalled yum processes,
so we have to do it ourselves. Below is my way of handling this issue:
bundle agent install_packages(pkg)
{
...
processes:
centos::
"yum"
comment => "handle stuck yum processes",
process_select => bored_yum,
signals => { "term" };
}
body process_select bored_yum
{
ppid => irange("1", "1"); # parent is dead, init-owned
tty => "pts/.*"; # do not touch user processes
stime_range => irange(ago(0,0,0,0,20,0),now); # minutes
process_result => "ppid|!(tty|stime_range)";
}
