does udev make /dev/ttyS0 ?
I am having problems making /dev/ttyS0 during startup. The physical device exists and the bios monitor reports it operational.
Where in the boot process is /dev/ttyS0 made?
udev is active and appears to make several devices. However I cannot determine exactly what it is doing.
Is udev supposed to make /dev/ttyS0?
I'm no expert on this by a long shot bt udev is suposed to be using the info in your sysfs
you got sysfs mounted in /etc/fstab ?
it should hhave a file in it named dev with the major and minor device numbers
should be able to type
udevinfo -q path -n ttyS0
perhaps we can go from here and diagnose further
Thank you - great help. On one system where it works the result is as expected. On the other that fails it is:
device not found in database
This yields the question "what database".
There are files in "/etc/makedev.d" and one of those calls for ttyS0 however that device is not being created.
What portion of the boot process should create that device?
Is there a log entry and which one?
