Red Hat Bugzilla – Bug 72217
ssh sessions hang after running "service"
Last modified: 2014-03-16 22:30:19 EDT
Description of Problem:
Certain daemons forget to close their descriptors.
The initlog (process.c) closes stderr and stdout but
forgets stdin. Thus, login sessions fail to exist if
/sbin/service was executed.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Log into a remote server, not running NFS by default.
2. Type "service nfs start"
3. Try to log out
Login session hangs due to attached stdin in a daemon.
Login sessions ending normally.
The code around process.c:runCommand() is not maintainable.
This can be worked around with a simple patch to the script,
but it seems proper to fix the problem in initlog, in order
to avoid surprises in the future.

Realistically, daemons should be fixed.
