Description Warren Togami 2006-01-21 22:53:37 UTC
QA discovered that /etc/sysconfig/spamassasin is being replaced during every
package intallation or upgrade.

# -a and --auto-whitelist options were removed from 3.0.0
# prevent service startup failure
perl -p -i -e 's/(["\s]-\w+)a/$1/ ; s/(["\s]-)a(\w+)/$1$2/ ; s/(["\s])-a\b/$1/'
/etc/sysconfig/spamassassin
perl -p -i -e 's/ --auto-whitelist//' /etc/sysconfig/spamassassin

Since FC3 spamassassin.spec %post contained this to remove user added options
during an upgrade from pre-3.0 SA that caused the new version to fail.  QA
discovered that this perl syntax actually creates another file and deletes the
original file.  This means that even if no change happens, the file has a
different timestamp and selinux security context.

Impact:
Not much, but it should be fixed some time in the future.

Fix:
This probably involves testing before doing the modification in order to avoid
an unnecessary replacement.  In the replacement case chcon is needed in order to
maintain the correct selinux context.
