Hi. It would be nice to have the line "ionice -c3 >/dev/null 2>&1" before (or after) "renice +19 -p $$ >/dev/null 2>&1" in /etc/cron.daily/prelink (line, 11) This assures the user isn't bothered with the io requests of the prelink process (class 3 = idle). If the kernel doesn't support ionice, the command will fail silently. Busy disk-io can render a (desktop) machine unusable, regardless of niceness level of the process. Thankfully CFQ can schedule IO. Reproducible: Always Steps to Reproduce:
`ionice -c3` doesnt actually do anything. you need to specify the pid with -p. http://sources.gentoo.org/sys-devel/prelink/files/prelink.cron?r1=1.6&r2=1.7
thank you
