Samba did not start when the file system was in read-only mode. With this update, the Samba init scripts no longer require write permissions for certain system files. Samba now runs as expected on read-only systems. (BZ#1195456)

Description Serge Droz 2015-02-23 21:20:03 UTC
Description of problem:
The init scripts for smb and nmb check if they are executed as root by checking if they can write to a file in /etc. If the filesystem is readonly this fails and samba wont start. 

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

samba-3.6.23-14.el6_6.x86_64

How reproducible:


Steps to Reproduce:
1. Put the system into ro mode (/etc/sysconfig/read-only)
2. reboot
3. 

Actual results:
Samba is not runing

Expected results:
Samba running

Additional info:

The fix is easy:

replace the line containing 
[ -w /etc/samba/smb.conf ] || exit 4
by 
[  `id -u` -eq  "0" ] ||  exit 4

in /etc/init.d/{smb,nmb}
