Description customercare 2012-07-12 08:01:51 UTC

Description of problem:

The trousers service got autoinstalled while upgrading from fc15 to fc16 with yum. Now it fails on boot and logs a lot of messages while trying to start :)

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

FC16 Kernel 3.4.4-4.fc16.i686.PAE #1 SMP
trousers-0.3.6-1.fc16.i686

How reproducible:

always

Steps to Reproduce:
1. get hands on fc15 without tscd
2. live upgrade via yum 
3. reboot 
  
Actual results:

Expected results:

a) not to get autoinstalled in the first place
b) be smart enough to check the env first.
   A PAE kernel indicates, that it's run on a VM and those do not have TPM chips.


Questions: 

is it safe to remove trousers from a vm running fedora , or do other parts of the os need trousers to be installed ?

Comment 1 Steve Grubb 2012-08-29 14:45:04 UTC

The 3.3 kernel disabled tpm. Its enabled again. Probably trousers got pulled in by dependency on some other package. Its not in the base install.
