Oddity when loading libreoffice onboot (core 16.2, x86_64)

(1/2) > >>

Leee:
I have a 2017 vintage HP Stream 11 ( Celeron N3060 @ 1.6 GHZ, 4 GB RAM ) with Tiny Core 14.0 installed. I use it primarily to run LibreOffice to access a simple spreadsheet and it works just fine.

I recently installed Core 16.2 in a dual boot config with 14.0 remaining in it's last-used condition - each version having its own installation directory and its own tce direcetory.  I used a copy of the onboot.lst from the old version to download all needed onboot extensions for the new version, with dependencies resolved at download time.  Then I brought forward a copy of mydata.tgz and other relevant files from the old version's tce directory to the new version's tce directory.  Everything works perfectly except...

When I boot up the new version, libreoffice.tcz, which is listed in onboot.lst, does not load.  However, once the system is up, I can tce-load -i libreoffice and it loads without problems and works perfectly.  All md5sums check out, the system is not short on RAM and storage device is 80% free.  Hexdump shows no unusual characters in onboot.lst.

Any idea what might cause perfectly good extension to not load onboot?

bitflip? somewhere? perhaps? maybe? whoknows?

nevertheless, bit-flips are interesting and thought-provoking(and thusly time-consuming):

@Leee, keep us posted on your investigation!

Leee:
Well... I still don't know -why- but apparently it just needs to try twice.

I moved libreoffice.tcz to the first line of onboot.lst - no luck.

Moved it to the last line - no luck.

Tried leaving it in its original position but also making it a dependency of another extension - THAT WORKED.

Reverted the modified dep file but simply put libreoffice into onboot.lst twice (on two consecutive lines, using copy and paste - so no typos in either entry) and THAT ALSO WORKED.


The first two tries above - I really didn't expect to work and they didn't... but then I really didn't expect the third and fourth tries to work either but they did.

You can add showapps to your kernel command line args so when booting it shows what tcz being loaded, and you maybe see whats wrong.

Add the bootcode:

--- Code: ---syslog
--- End code ---

Then check /var/log/messages (and /var/log/messages.0 if present) for errors
and/or warnings when it's loading extensions.

Maybe something in your backup is causing problems when restored?

That sounds suspicious. What other relevant files?

Although libreoffice has not changed from TC14 to TC16, its dependency tree has.

To see what changed ....
Take the .tree files and create sorted lists of all dependencies:

--- Code: ---awk '$1=$1' libre14.tree | sort -u > libre14deps
awk '$1=$1' libre16.tree | sort -u > libre16deps
--- End code ---

To see what got removed:

--- Code: ---rich@tcbox:~$ diff -u libre14deps libre16deps | grep -E "^\-"
--- libre14deps 2025-11-13 13:43:18.000000000 +0100
-aspell-en.tcz
-atk.tcz
-at-spi2-atk.tcz
-gnutls35.tcz
-libEGL.tcz
-libICE.tcz
-libSM.tcz
-nettle3.tcz
-openssl-1.1.1.tcz
rich@tcbox:~$
--- End code ---

To see what got added:

--- Code: ---rich@tcbox:~$ diff -u libre14deps libre16deps | grep -E "^\+"
+++ libre16deps 2025-11-13 13:43:28.000000000 +0100

You might also want to let your system run an update:

--- Code: ---tce-audit builddb
tce-audit updatedeps
tce-audit fetchmissing
tce-update
exitcheck.sh reboot
--- End code ---

I think the system creates a tce/optional/update directory if you want to see
what might change before running the  exitcheck.sh reboot  command.

Maybe some interaction with one or more  /usr/local/tce.installed/  scripts?

That's also a good idea.
