separating own tcz's from repo tcz's
« on: October 17, 2015, 02:08:48 PM »
create own tcz

in /optional, mkdir yourdir (for me it was, "mine").

cp own tcz to /optional/yourdir

edit onboot.lst if desired. for me, an example is tmux, so in onboot.lst i have:

mine/tmux.tcz

reason/benefit:

I've been floundering about building stuff and got lost; forgot what was mine. Now I know.

Nice trick. Just tried it and found that Apps doesn't, unfortunately, recognize the sub-directory if wanting to manage OnBoot/OnDemand via GUI. I do something similar, just prepend extensions with PE (personal extension, eg PE-SMPlayer.tcz) and keep them in /optional proper. Easy fo find, just scroll down to the 'P' section.

Right, no explicit support for subdirs, so things may break.
The only barriers that can stop you are the ones you create yourself.

Hi,
I'm using and testing this since ttz posted it (thanks), with just a slight modification, I symlink the extensions to  ../optional  and there I create a new  *.tcz.md5.txt  file, so updating anything that depends on extensions which I have replaced with custom versions, won't fail due to md5 sum mismatch.
Installing new extensions is another story though - this still needs the original  *.tcz.md5.txt  file as it is on the repo server.
But this means less work is involved from my side compared to creating extensions with different names with the risk of loading one app twice or just replacing the extensions and wasting disk space by keeping backups (which would still produce md5 sum mismatches).

I think that's a quite good solution for using custom extensions and, at the same time, protecting them from being 'updated'.

This is my current  /usr/bin/tce-setup  with an added boot code to automate the symlinking:
Code: [Select]
#!/bin/busybox ash
#(c) Robert Shingledecker 2009-2011
# Stuff added by Misalf...
# + Cosmetics.
# + New boot code: lsts=
#   Based on code from tinycore forums user theYinYeti.
#   Loads extensions from additional .lst files before loading "onboot.lst" or lst="foo.lst".
#   Example: lsts=Xorg.lst,nvidia.lst,whatever.lst,...
# + New boot code parameter: showapps=xyz (For now, any value has the same result).
#   Displays currently processed .lsts while booting (see lsts= boot code) when not using "showapps" boot code (without ="value").
# + Don't delete upgrade directory but only its content ("$TCEDIR"/optional/upgrade/*). (laziness won't stop my productivity!)
# + New boot code: override
#   Creates symlinks from  "$TCEDIR"/optional/override/*.tcz  to  "$TCEDIR"/optional .

I'm not aware about the actual update and install procedures and how/when which md5 sum files are used (remote or local), so I wasn't able to think about a way to make Core being able to handle custom extensions. Would be nice if it could be done.
Anyone had a look at that already? Any ideas?

Uhm, while writing this.. Maybe it would be enough to just check if the  *.tcz.md5.txt  file is a symlink, and if so, ignore its content and continue with the next  *.tcz.md5.txt  - The user would be responsible for any version mismatches or any mess anyway.
