>Description:
	The vacation command tries to chdir() to the account's home dir.
	This fails on a mail server where home directories are not mounted.
	It looks to me the failure can be (silently) ignored if both the
	database and message files are given as absolute paths.
>How-To-Repeat:
	run vacation for a user with no home directory.
>Fix:
The following patch ignores chdir() failure if both dbprefix and msgfile
are absolute paths. I hope this has no further implications on the invocation
of sendmail later.
Maybe you don't want to try the chdir() in the first place, e.g.
	if (dbprefix[0] != '/' && msgfile[0] != '/' && chdir(pw->pw_dir)) {
or want to log the failure at a lower level, e.g.
	if (chdir(pw->pw_dir)) {
		if (dbprefix[0] != '/' && msgfile[0] != '/')) {
 			syslog(LOG_INFO, "%s: no such directory %s.",
	 		    getprogname(), pw->pw_dir);
		} else {
 			syslog(LOG_ERR, "%s: no such directory %s.",
	 		    getprogname(), pw->pw_dir);
 			exit(1);
		}
	}
