Description Martin Poole 2005-04-20 07:31:27 EDT
Description of problem:

mkinitrd honours umask.

If the user has set a umask in their .bashrc (or even globally) that quashes the
execute bit then the binaries copied to the image lose their execute bit and
fail to run at boot.

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

How reproducible:

Steps to Reproduce:
1. put 'umask 0111' in /root/.bashrc
2. create an initrd
3. boot it.
Actual results:

no modules load

Expected results:

modules should load.

Additional info:

script should probably force umask, and possibly even use -p on the copies so
the datestamps match original (allows easy matchup).
Comment 1 Peter Jones 2005-05-03 14:56:50 EDT
-HEAD now sets umask itself.
