Well, we need to see the information netconfig had at this point. In the
 directory /run/netconfig there should be subdirectory for each interface;
 each subdirectory will have multiple files, one for each "service" that
 modified interface configuration. These should be preserved as well.
 Actually I would simply save the whole /run/netconfig (which also captures
 generated resolv.conf).
Ok, will run a zip command from the script.
function write_resolv_conf()
...
     TMP_FILE=`netconfig_mktemp "$ROOT$DESTFILE" 0644 0755` || return 3
     if ! dump_resolv_conf "$@" >> "$TMP_FILE"   ; then
         rm -f -- "$TMP_FILE" ; return 3
     fi
     if cmp -s -- "$TMP_FILE" "$ROOT$DESTFILE"   ; then
         rm -f -- "$TMP_FILE" # unchanged
     elif mv -f -- "$TMP_FILE" "$ROOT$DESTFILE"  ; then
         changed=1
         #CER
         MYDATE=`date --rfc-3339=ns`
         #cp "$ROOT$DESTFILE" "$ROOT$DESTFILE$MYDATE"
         zip -r "/run/netconfig_$MYDATE.zip" /run/netconfig/*
     else
         rm -f -- "$TMP_FILE" ; return 3
     fi

And it is working.

I guess I should wait a bit more.

No change.

Ah! now it changes. It is 20:59.

Saw that before, it stays fixed for some minutes, then it starts moving.

I suppose you want to compare the run/netconfig/eth0/netconfig0 or run/netconfig/eth0/netconfig1 files?

On "1" and "2" they are identical.

Between 2 and 3 there is a change.

cer@Telcontar:~/tmp/Andrei/run-3/netconfig/eth0>

So, version 3 doesn't have dns entries.
version 4 gets them again: DNSSERVERS='2a02:9000::aaaa 2a02:9000::bbbb'
Version 5 is identical (in those two files).

Version 5 has resolv.conf:

search valinor
nameserver 127.0.0.1
nameserver ::1

while version 4 has:

search valinor
nameserver 127.0.0.1
nameserver ::1
nameserver 2a02:9000::aaaa

If you want the zip files to inspect them yourself, just ask.

Well, whatever the cause, I can not use the automatically generated 
dynamic resolv.conf file.

If you think there is something I can tell the ISP, I will, but they will 
probably say nothing back.
