My experience with fsck is that it runs in the background and does not
seem to take additional time. Although, usually, it just checks the
file system logs and says everything is fine.
Experimenting with reducing boot times, I found that if you comment out
the line pertaining to finding usb updates in linuxrc-sdroot on the
initrd partition of the SD card it shaves ~ 23 seconds off of the boot
time. Of course, you then lose USB functionality on the board. Also,
if you turn off some of the scripts in /etc/rc2.d (S10sysklogd,
S11klogd, S21nfs-common, S91apache2, S99startx) on the root file system
partition, you can save another 7 seconds on the boot time at the
expense of losing NFS and syslogging.

Hi,
The network connection is not used , and the SD card image is
basically identical with the one provided by TS .
So you think if I disable network services I would see a decrease in
boot time?
We already know about fsck taking a long time.
Thanks

Harry,
Do all of these boards have network connections? I've noticed some
debian services like mtd take much longer to start while they timeout
on a network connection. Are all of the SD cards the same speed
class? It may also be that if they have been powered up a different
number of times some could be running a filesystem check.
Best Regards,

Have anyone seen this before?
Thanks
