Description of problem:
I'm getting undefined symbol: __set_errno in /lib/libnss_db.so.2 during
shutdown, as well as during other operations, after update to nss_db-2.2-12
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Do nearly anything that causes a call to /lib/libnss_db.so.2
2.Error "/lib/libnss_db.so.2: undefined symbol: __set_errno" is displayed
Actual Results: Error is displayed
Expected Results: No error is displayed an operation completes
I only noticed this start happening after updating using up2date on 04/12/02.
The nss_db package wasn't updated during that session though, so far as I can
tell. I was able to boot the cd, run linux rescue and delete the symlink to
/lib/libnss_db.so.2.0.0. The link keeps getting re-created, and the error keeps
returning. Removing the nss_db* packages eliminates the error, but I can't
figure out what this will break as there don't seem to be any deps, but the
package must be there for something, yes?
The nss_db package is mainly used to speed up nsswitch operations on hosts where
the flat files in /etc are unusually large, and is never required for proper
operation. You should be able to uninstall the package without difficulty.
The breakage should be fixed in nss_db-2.2-14 and later (I missed one symbol
when patching it to build with newer libc versions). Thanks!
