OpenWrt should support an optional /etc/profile.d directory like
most other Linux distributions. This allows packages to install
their own scripts into /etc/profile.d/ directory.
The file suffix should make clear, that these scripts
are (sourced) shell-snippets. If the user needs e.g. php or lua,
one must make sure that the interpreter is called.
The reverse failsafe test makes sure, that the effective returncode is 0.
A typcal usecase is the inclusion of private helpers,
special variables or aliases, which at the moment needs
patching the sourcecode and is not well maintainable.
Now the builder can simply add there files.

Current NAND sysupgrade process is a bit hard to follow due to the way
of triggering stage1. Currently this is done by leaving a /mark/ in the

Existence of this mark stops standard sysupgrade process (as the result
of sysupgrade_pre_upgrade exit). This may be a bit misleading.

This restores normal pre-r43715 200ms blink-period for the System LED we're all accustomed to see while our OpenWrt routers are booting.
Failsafe possibility will now be signalled with a new 100ms blinking, which is easily recognizable from the normal 200ms booting.
So no existing user will be scared by a new 500ms LED pattern, since such a slow pattern could easily be mistaken for something wrong... I was like "ok why my router is collapsing now, is this a bad flash, a kernel panic, or what else" when I've seen it for the first time ;)
Sorry for not having explained myself better in v1 of this patch.

different architectures for eglibc:
eglibc-2.19-r25243$ grep -r "ld-soname :=" . | awk '{ print $3 }' | sort -u
ld64.so.1

ld-linux-x32.so.2
ld-linux-x86-64.so.2

replace the awk script with a sed script to extract it properly and
drop the hardcoded so-name.

Based on bug #18206 sysupgrade can lead to loss of password information in

https://dev.openwrt.org/ticket/18206
Currently /etc/shadow is defined as a conffile in base-files:
https://dev.openwrt.org/browser/trunk/package/base-files/Makefile#L37
But it is not defined in the default list of essential files to keep in
sysupgrade:
https://dev.openwrt.org/browser/trunk/package/base-files/files/lib/upgrade/keep.d/base-files-essential
If exporting conffiles info fails, /etc/shadow can get lost.
Shadow passwords are now the default, so saying that preserving /etc/passwd
is essential while /etc/shadow is not, makes no sense.
The attached patch adds /etc/shadow to the list of essential files.

However on some boards, the MAC addresses are stored

are using hyphens or dots as separators instead of
colons. Also the leading zeroes may be missing from the
individual octets or those are replaced with spaces.
Add a new function which can be used to convert these
