Hi!
How can I track all the filesystem access made by system at boot time?
In other words when is the earliest I can launch stap with my stp script
during bootup?
I could think of /etc/rc.local or /etc/rc.sysinit.
Will that be good enough? Any ideas?
Thanks

Either of those should work. Our colleague Dan Berrange has gone one
step farther <http://people.redhat.com/berrange/systemtap/bootprobe/>.
Plus we're planning to make it possible for a systemtap module to be
compiled right into a kernel boot image, so that it can probe the
kernel even before user-space init is run.
