Tomas - I'm taking the liberty of Cc:ing the devel list (you suggested that
you had spoken with some of them) but would thank you for the 'off-list'
exchange of emails.
I have spent quite a bit of time checking various
possibilities/combinations to ensure that a user cron, re-indexing zebra,
functions as expected on various combinations of Koha 3.6.x and 3.8.4 on
Ubuntu 10.04 and 12.04 (the two current Ubuntu LTS servers) on both 32- and
64-bit boxes.
I have come to the conclusion that the use of crontab as outlined in RESULT
[B] "rewritten" (see below) is fully functional, is a single "edit" at the
time of installation, and could be included with total clarity in
INSTALL.ubuntu and on the Wiki. The use of cron.d/koha RESULT [C] "second
scenario" is also functional, but requires two edits at install time (and
I've included a couple of minor caveats.)
I have not looked at the "package", only at various tarballs, so do not
know under what conditions either crontab or cron.d may be used. ISTR
reading that package and tarball directory structure differs, so am not at
all certain how close the two "installs" should or could be maintained.

NOTES:
[A] From $ man cron :
"cron also reads /etc/crontab, which is in a slightly different format
(see crontab(5)). Additionally, cron reads the files in /etc/cron.d: it
treats the files in /etc/cron.d as in the same way as the
/etc/crontab file (they follow the special format of that file, i.e.
they include the user field). However, they are independent of
/etc/crontab: they do not, for example, inherit environment variable
settings from it."
[B] From 3.8.4 INSTALL.ubuntu :
5.2.2 Zebra Indexer
Add an entry in Koha user crontab to scheduled added/updated/deleted records
indexing by Zebra with this command:
<path/to/koha>/misc/migration_tools/rebuild_zebra -z -b -a
[C] From <http://wiki.koha-community.org/wiki/Koha_on_Ubuntu> [abbreviated]
3 - Setup the environment variables used by Koha scripts
$ sudo gedit /etc/cron.d/koha
Add
KOHA_CONF=/etc/koha/koha-conf.xml
KOHAPATH=/usr/share/koha
PERL5LIB=$KOHAPATH/lib
(Alternatively ... same result.)
$ sudo gedit /etc/bash.bashrc.local
Add
export KOHA_CONF=/etc/koha/koha-conf.xml
export PERL5LIB=/usr/share/koha/lib
5b - Reindexing Choices
Option #1: See
http://wiki.koha-community.org/wiki/Background_indexing_with_Zebra
Option #2: Add a cronjob to index your zebra database.
$ sudo gedit /etc/cron.d/koha
Add
# The cronjobs
*/5 * * * * koha $KOHAPATH/bin/migration_tools/rebuild_zebra.pl -a -b
-z &> /dev/null
RESULTS:
[B] above does not funtion. It does function if rewritten as:
5.2.2 Zebra Indexer
Add a Koha user cron job to schedule added/updated/deleted record indexing
by Zebra with this command:
$ sudo vi /etc/crontab
Append the following lines:
KOHA_CONF=/etc/koha/koha-conf.xml
KOHAPATH=/usr/share/koha
PERL5LIB=$KOHAPATH/lib
*/1 * * * * koha $KOHAPATH/bin/migration_tools/rebuild_zebra.pl -a -b
-z &> /dev/null
:x
[C] {5b Option 1 - respectfully for Frédéric - not explored "This solution
is completly outside Koha"}
First scenario: para 3 "cron.d" plus para 5.b Option 2 does not function
(probably due to [A])
Second Scenario: para 3 "Alernatively" plus para 5.b Option 2 does
function, with two possible caveats:
(a) Comparing my notes from various "new installs" versus "sandbox testing
edits", I suggest adding 'export KOHAPATH=/usr/share/koha' to .bashrc
between the other two en vars
(b) For a [user] cron, I prefer to 'export' from /home/[user]/.bashrc
rather than /etc/bash.bashrc.local
