Udev creates the external usb hard disk device node too late
on my debian lenny OS I have an external usb hard disk I would like to automount it at boot.
So I edited the /etc/fstab file in order to automount /dev/sdb1. It worked without problem.
Then I recompiled the kernel and, as consequence, /dev/sdb1 changed to /dev/sdc1. I started playing with udev in order to match the now called /dev/sdc1 and to change its name in /dev/maxtor (being maxtor the brand of the hard disk). Obviously I edited also /etc/fstab: /dev/sdb1 is now /dev/maxtor.
The boot automount doesn't work anymore. On the boot sequence I can read the message "Mounting local filesystem...mount: special device /dev/maxtor does not exist FAILED".
But when I log into the system I can run the command "mount /dev/maxtor /mnt/maxtor" and it works! So, IMHO, my udev rule is correct otherwise also the manual mount wouldn't work, right?
How can I fix this? I have to tell to udev to create /dev/maxtor BEFORE the boot automount process.
Thank you in advance,
Update: I tried to delete my udev rule and to edit /etc/fstab changing /dev/maxtor in /dev/sdc1 (the name udev gave to my hard disk after kernel recompile, before was /dev/sdb1) and it didn't work: on boot process I always see the "Mounting local filesystem...mount: special device /dev/sdc1 does not exist FAILED".
Then I tried to change /dev/sdc1 in /dev/sdb1 in /etc/fstab and to reboot with the old original kernel and int this way it works. This is a weird problem, now it seems related to kernel change. With my compiled kernel, the OS seems to have lost the capacity to detect my device node correctly...any clues???
