Tomas,

I added "pre-up echo $IFACE >> /tmp/interfaces_test" line to each
interface configuratio file in /etc/network/interfaces.d/ and looks
like the invoke order is not lexical. I have four files in
/etc/network/interfaces.d/:

# ls -l /etc/network/interfaces.d/
total 16
-rw-r--r-- 1 root root 338 Aug 26 14:10 br0
-rw-r--r-- 1 root root 555 Aug 26 14:10 eth0
-rw-r--r-- 1 root root  96 Aug 26 14:09 eth0.100
-rw-r--r-- 1 root root 109 Aug 26 14:09 lo
#

However, the content of the /tmp/interfaces_test is alwayse(I rebooted
the machine 5 times) following:

# cat /tmp/interfaces_test
br0
lo
eth0
eth0.100
#

I thought that ifup processes those files in order which they appear
in /etc/network/interfaces.d/*, but this does not seem to be true. Any
other ideas?


thanks,
Martin
