Description Russell Coker 2004-07-02 03:11:54 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (compatible; Konqueror/3.2; Linux) (KHTML, like Gecko)

Description of problem:
If /dev/mapper/control exists with the correct major and minor numbers then it should not be removed and re-created, it should be left as-is.

nash should stat /dev/mapper/control first and do nothing if it discovers that the device node exists in the way it should.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
Boot the machine and observe that the device node is recreated.

Expected Results:  When I boot twice with the same kernel (so there are no changes to the major/minor numbers) then the device node should not be changed.

Additional info:

This is a minor bug, but I really don't want needless writes to /dev.

Comment 1 Jeremy Katz 2004-08-02 22:24:15 UTC
nash >= 4.0 won't create it if it already exists and matches the
correct major/minor.  initscripts will still need to not remove it.

Comment 2 Bill Nottingham 2004-08-03 03:27:35 UTC
Changed, will be in future releases. Of course, has to conflict with
mkinitrd < 4.0 now. :)
