Hello
7 years later I've faced the same problem.
This is how script should start nfcapd:
+ start-stop-daemon --start --quiet --pidfile /var/run/nfcapd.pid
--exec /usr/bin/nfcapd -- ... -x '/root/nfrotate-args %f'
If we check command line in /proc/<pid>/cmdline, we can see:
00 2D 78 │ 00 2F 72 6F │ 6F 74 2F 6E │ 66 72 6F 74 │ 61 74 65 2D | 61
72 67 73 │ *20* 25 66 00 || -x./root/nfrotate-args %f.
"0x00" is the delimiter between args, 0x20 (space) is the delimiter
between command and arguments for -x option
Default init script does this:
DAEMON_ARGS=" ... -x '/root/nfrotate-args %f'"
+ start-stop-daemon --start --quiet --pidfile /var/run/nfcapd.pid
--exec /usr/bin/nfcapd -- ... -x ''\''/root/nfrotate' '%f'\'''
From /proc:
2D 78 │ 00 27 2F 72 │ 6F 6F 74 2F │ 6E 66 72 6F │ 74 61 74 65 | 2D 61 72
67 │ 73 *00 *25 66 │ 27 00 || -x.'/root/nfrotate-args.%f'.
Delimiter between command and argument - 0x00, not 0x20, so nfcapd does
not see %f, and it thinks it does not belong to -x option
I'm not very good at init scripts, so the only way I've found is add
options in default file for command and it's arguments.
