| OS: | Linux | |||
| Whiteboard: | ||||
| Fixed In Version: | chkconfig-1.7.3-1.el7 | Doc Type: | Bug Fix | |
| Doc Text: |
Cause:
There was a feature in alternatives that changed the format of alternative state files. This change was not forward-compatible, which means that you can't use a state file modified with new alternatives with old alternatives binary.
Consequence:
This is a problem during the downgrade of alternatives. The new version changed the file and after downgrade the old version is not able to read them.
Fix:
During downgrade of new version we alter the state files to match the old format.
Result:
Working downgrade.

This is not something that should be done in chkconfig package. The java packages that use the --family option should have a dependency for new chkconfig and when you removed them this alternative should be removed. My first idea of how to fix it, only in the newer java package would be to have a: %triggerin -- chkconfig < 1.7 followed by a scriptlet to rerun all alternatives commands, but not using the --family option (or a really ugly 's/@[^@]+@//' in the alternatives file). Do you have a different suggestion? I mean, to be able to downgrade in the same transaction java-1.8.0-openjdk and chkconfig. Ok so what we could do is to add this trigger in chkconfig spec file:
diff --git a/chkconfig.spec b/chkconfig.spec
index 4e08ff4..15eccca 100644
--- a/chkconfig.spec
+++ b/chkconfig.spec
