This change ensures that /etc/init.d/* scripts are started with

reads (e.g. by mistake) from stdin, which a user can perceive as if
some characters typed into shell on serial console are "eaten" by

is very annoying, because each character needs to be pressed several

procd: Don't use syslog before its initialization
When procd starts a rcS script, it captures its stdout and stderr and
logs them via syslog(). The problem with that is that the rest of
procd code uses ulog rather than syslog() directly and ulog_open()
doesn't call openlog() immediately, but only after something is logged
with ulog(). This lazy calling of openlog() can result in the
following unwanted behavior:
1) When rcS's stdout/err is logged via syslog(), the log identifier is
not set yet (due to openlog() not called) and so the log message
lacks information about source.
2) procd can also log stdout/err from services. When a message from a
service needs to be logged, ulog_open() is called to change the log
identifier to match the service name/PID. After logging the service
messages, ulog_open() is called again the change the identifier
back to "procd". The lazy call to openlog() means that the messages
logged directly with syslog() will be logged with the
identification of the previously logged service and not of the rcS
script that produced the message.
Both problems are fixed by replacing direct call to syslog() with
ULOG_NOTE, which automatically calls openlog() if needed.

root@OpenWrt:~# uci show system.ntp

system.ntp.use_dhcp='1'
system.ntp.dhcp_interface='wan'

network.wan.proto='dhcp'
network.wan.ifname='eth4'
network.wan.reqopts='1 3 6 15 33 42 51 121 249'
2) if obtained DHCP lease has an option 42 sysntpd service will have an
instance
3) run "ifup wan"
4) although the same DHCP lease was obtained, sysntpd would be stopped
Because sysntpd service is deleted when last instance is freed, its triggers
will also be released. Without these triggers in place, sysntpd will not be
reloaded when a new DHCP lease containing option 42 will be received.

The easiest solution is to use tm_gmtoff from struct tm. Unfortunately

Alternative (worse?) solutions:
1) Use timegm that is nonstandard GNU extension
2) Work with TZ env (getenv & (un)setenv) that is not thread-safe
3) Use timegm (next to localtime) and implement function comparing two

utils: add patch_fd() and patch_stdio() helpers
Introduce two new helper functions to deal with stdio redirecation in a
uniform, reliable manner:
The patch_fd() function will attempt to redirect the given fd number to the
specified file, using the supplied flags for the open() syscall. When the
device is NULL, "/dev/null" is asumed, when the device is a relative path,
openat() is used to open it relative to the "/dev" directory. When the device
cannot be openend, a fallback to "/dev/null" is attempted.
The patch_stdio() function is essentially a wrapper around patch_fd(),
providing an easy interface to redirect stdin, stdout and stderr to the same
given device.
Both function return 0 on success and -1 on error. The errno variable will
be set accordingly.

not in /lib64, and /lib64 is a symlink to /lib, so ujail find
all the libs in /lib64, add them in the jail (only under /lib64)

uClibc (openwrt CC r47608 x86-64) looks for lib in /lib and
