[Bug 369550] Re: /etc/init.d/virtualbox-ose wastes 10 seconds with find /lib/modules

[Daniel Hahler]

Thank you for your investigation and proposed solution. This sounds like
a great improvement in boot time.

I'm looking into getting it fixed in Karmic and forwarded to Debian.


My results (please note that you should use "sudo" for the modprobe call):

$ echo 3 |sudo tee /proc/sys/vm/drop_caches
3
daniel at base { ~ }
$ time sudo modprobe -n -q vboxdrv

real    0m2.076s
user    0m0.008s
sys     0m0.004s
daniel at base { ~ }
$ echo 3 |sudo tee /proc/sys/vm/drop_caches
3
daniel at base { ~ }
$ time find /lib/modules/`uname -r` -name "vboxdrv\.*" 2>/dev/null|grep -q vboxdrv

real    0m9.875s
user    0m0.028s
sys     0m0.072s
