[Pkg-sysvinit-devel] Bug#546245: sysvinit: /etc/nologin symlink deleted by /sbin/shutdown

[Mark Eichin]

Package: sysvinit
Version: 2.86.ds1-61
Severity: normal

When looking at some etch->lenny upgrade diffs, noticed that while the
sysvinit postinst creates a symlink from /etc/nologin to
/var/run/initscripts/nologin, the first "shutdown" after the upgrade
(or install) simply deletes the symlink.

sysvinit-2.86.ds1/src/paths.h:
        #define NOLOGIN		"/etc/nologin"		/* Stop user logging in. */
sysvinit-2.86.ds1/src/shutdown.c, shutdown():
	unlink(NOLOGIN);

(Maybe this should reopen Bug#191041 which introduced the use of
 /var/run, but that's from 2003 and archived... also, pam also looks at
 /etc/nologin directly, perhaps the symlink change should just be reverted?)
