* init.d-mandos (Required-Start, Required-Stop): Bug fix: Added
"$syslog", thanks to Petter Reinholdtsen
<pere@hungry.com> (Debian bug #546928).
* initramfs-tools-script: Removed erroneous comment.
* plugins.d/askpass-fifo.c: Removed TEMP_FAILURE_RETRY since it is
not needed.
* plugins.d/mandos-client.c (main): Bug fix: Initialize
"old_sigterm_action".
* plugins.d/splashy.c (main): Bug fix: really check return value from
"sigaddset". Fix some warnings on
64-bit systems.
* plugins.d/usplash.c (termination_handler, main): Save received
signal and
re-raise it on
exit.
(usplash_write): Do not close FIFO, instead, take an additional file
descriptor pointer to it and open only when needed
(all callers changed). Abort immediately on EINTR.
Bug fix: Add NUL byte on single-word commands.
Ignore "interrupted_by_signal".
(makeprompt, find_usplash): New; broken out from "main()".
(find_usplash): Bug fix: close /proc/<pid>/cmdline FD on error.
(main): Reorganized to jump to a new "failure" label on any error.
Bug fix: check return values from sigaddset.
New variable "usplash_accessed" to flag if usplash(8) needs
to be killed and restarted. Removed the "an_error_occured"
variable.
