>Description:
	At umich.edu, we have a convention of using timestamps in
	logfile names.  Currently, we have hard-coded logic
	in kerberos to construct filenames of the form
	<utility>.log.YYYYMMDD .  This is obviously very site
	specific, yet we'd rather not maintain site specific logic.
	It would be nice if log file names could be expanded via strftime.
>How-To-Repeat:
	Run any kerberos daemon more than once.  Watch it reuse
	the same log file.
>Fix:
	Compile-time fix, apply the patch in
	/afs/umich.edu/group/itd/build/mdw/krb5.15x/patches/krb5-1.6.3-logts2.patch
	configure with new --enable-logfile-by-date .
	Change krb5.conf [logging] stanza, log file lines
	to read like: FILE:/var/log/krb5kdc.log.%Y%m%d .
	Restart daemons.  Now see new style logfile names.
