Hi,
IIRC, the problem was that all the syslog packages were providing
${sysconfdir}/init.d/syslog which caused problems. And I don't think that has
changed.
Why would you want to install two syslog daemons on the system? You should be
able to install busybox after syslog as busybox-syslog is packaged in separate
binary rpm.
Cheers,
Markus

I think the previous commit (syslogd: don't use update-alternatives) is
made because syslog daemon conflict with each other. I guess the author
assumed that the 'syslogd' and 'klogd' alternatives entries are handled
by busybox-syslog package.
On the other hand, I think the patch is trying to solve the problem of
busybox being installed after sysklogd.
We are currently not seeing errors because busybox is likely to be
installed before sysklogd. Even in this situation, the result is not all
correct, because the links busybox's postinstall creates are covered by
the real binaries from sysklogd.
I think the problem is about busybox's handling of alternatives.
Khem, I've sent out a patch to fix busybox's alternatives logic. Could
you please help review it?
Best Regards,
Chen Qi
