Description Zdenek Kabelac 2012-05-25 09:22:35 UTC

Description of problem:

Todays rawhide upgrade for glibc-2.15.90-2.fc18.x86_64 is causing some problems - one of them is that my link file /etc/localtime pointed to ../usr/share/zoneinfo/US/Eastern, while I'm pretty sure it's been pointing to ../usr/share/zoneinfo/Europe/Prague before the update.

Changing the link back to right place fixed display of time again with proper time zone.

Version-Release number of selected component (if applicable):
glibc-2.15.90-2.fc18.x86_64

Zdenek, what are the contents of your /etc/sysconfig/clock?  

The trigger script should extract the timezone from /etc/sysconfig/clock and fix /etc/timezone appropriately.  I did some simple sniff testing of that code as part of the update, so I'm rather surprised you ran into this problem.

Comment 2 Zdenek Kabelac 2012-05-25 16:19:35 UTC

# ls -la /etc/sysconfig/clock 
-rw-r--r-- 1 root root 159 29. říj  2008 /etc/sysconfig/clock


# cat /etc/sysconfig/clock 
# The ZONE parameter is only evaluated by system-config-date.
# The time zone of the system is defined by the contents of /etc/localtime.
ZONE="Europe/Prague"


I'm really not sure what happened - I'm just describing the situation
after booting my system after 'yum upgrade' - when I've noticed
I'm in the ETD time zone. I'm not sure who changed the link,
so I just filed the bugzilla agains link owner - glibc.

Here is the portion of yum log from today - and as you may see something time-weird happened right after glibc-common update -  10 -> 4

Comment 3 Jeff Law 2012-05-25 21:09:38 UTC

Thanks.  Further research has shown this is a known issue.  If a file marked %config(noreplace) changes from a file to a symlink, RPM silently replaces the file with the symlink without creating a .rpmsave.  Joys.   I'll work around this bit of RPM braindamage.
