Found it. Skeleton for exegnu is in /etc/exegnulinux :) Anno domini 2020 Tue, 6 Oct 16:01:58 +0200 Dr. Nikolaus Klepp scripsit:

hi all! I'm currently stuck at my remastering of exegnulinux. This is what I've got: - HD installation, customized to my needs. - TDE customized for "user" - TDE configs moved to /etc/skel/.trinity (removed the old exe config) - /usr/lib/adduser.local to customize installation for new users I can create a iso with "refractasnapshot" and it works - almost. The ISO is bootable, but the TDM startup theme is the default exegnulinux theme, as is the desktop theme and .bashrc. As far as I can tell, the skeleton files from "exegnu-userdefaults-trinity" are copied over my user-files. Does anybody know where exegnulinux hides the sketon/template for the live user? Does it redownload the files? I'm puzzled, 'cause I replaced all the skelton files from "exegnu-userdefaults-trinit" with my version, but it did not help. Nik

Nik, Exegnu is designed to be pure devuan with TDE and a few other additions, mostly as custom deb packages.. exegnu-userdefaults-trinity (description incorrectly says jessie, its now for beowulf>) is the one which does what it suggests (including skel configs) root@vaio:/# dpkg -l|grep exegnu ii exegnu-installer 3.0.3 all Installer for Exe GNU/Linux (Devuan with Trinity Desktop Environment) ii exegnu-keyring 1 all exegnulinux archive keyring ii exegnu-oxygen-icons 3.0.0 all Oxygen Icon Theme for Trinity Desktop ii exegnu-trinity-themes 3.0.3 all Exe GNU/Linux Ksplash and Wallpaper for Trinity Desktop ii exegnu-userdefaults-trinity 3.0.3+1 all Exe GNU/Linux User Defaults for Debian/Devuan Jessie with Trinity Desktop. ii live-boot 1:20190614+exegnu1 all Live System Boot Components ii live-boot-initramfs-tools 1:20190614+exegnu1 all Live System Boot Components (initramfs-tools backend) ii pmount 0.9.99-alpha-1+exegnu1 amd64 mount removable devices as normal user ii straw-viewer 0.0.3-2~exegnu1 all Search, stream and download YouTube content. live-config-trinity is the other one, this sets the live-config functions for TDE (for a live system), which is unsupported in the mainstream. The rest are packages not available elsewhere or rebuilds with extra functionality and none are essential. BTW Exegnu is built from a clean bootstrap and isn't actually Refracta-based. Although I have been involved also with Refracta and of course include some of the excellent Refracta tools in exegnu. Cheers, D

Thank you for the explanation. I managed to customize exegnu. Right now I'm stuck at the exegnu-installer :) This is what I've done: - changed /lib/live/config/0050-locales and /lib/live/config/1066-trinity-lang to default to de_DE (insted of en_US). - PREEMPT-RT kernel - LinuxCNC + html docs + smictrl + KiCad ... - TDE configured to my needs - removed the content of /etc/exegnu/skel (all the relevant settings are in ~user) - made /etc/skel to match my users config including .trinity (this might be an error, but I think it's not) - made /usr/local/sbin/adduser.local to take care of the specialities from /etc/skel - made a folder ~/tool/ with F-Engrave + G-code_ripper + dmap2gcode + pcb2gcodeGUI + dxf2gcode + PyCAM - made custom menu for the tools Then I built a ISO with refractasnapshot. The resulting ISO works as expected - ~/tools is present, menu is there etc. But when I run the installer, the additionons are gone. Basicly it looks like the user directory is wiped clean and restored from /etc/skel and /etc/exegnu/skel - wich I think is what is actually going on. So now I'm working my way through exegnu-installer to see how I could make my "new" user identical to the user of the ISO. When this is done I have a fine image for my lectures - and anybody who wants exegnu remastered with linuxcnc is wellcome to test :) BTW, there is a bug in 1067-exegnu-userdefaults, line 48: SYSTEMLANG=$(cat /etc/default/locale|grep -m 1 'LANG='| sed 's/LANG=\"//'| sed 's/[A-Z].*//') As /etc/default/locale does not have a <"> the spanish version is never used. What I am now struggling with (besides the installer) is an easy way to make my modifications to the various refracta/live/exegnu-packages kind of persistent - i.e. make it survive a package reinstallation.

Cheers Nik, I see you (mostly) worked out your remaster issues yourself! Well done, and thanks, because you also raised a few issues with the default exegnu image that need sorting but I had missed. It needs to work out-of-the-box with refractasnapshot. Re language: The correct way to set language is with a boot parameter on cmdline, e.g. lang=de (parsed in live-config script 1066-trinity-lang) OR the Debian way, locales=de_DE.UTF-8 keyboard-layouts=de .. no need to edit those scripts. It only defaults to en_US if nothing is specified or if it is unspported. Of course the appropriate TDE language pack should be installed, e.g.tde-i18n-de-trinity. Which it isn't on the default iso, multiple language packs would make the iso very large! The exegnu installer needs patching to show "clone" mode properly. It's looking for a file "/etc/snapshot-id", from a previous experimental snapshot version no longer in use. That should in turn fix the skel issue for a snapshot installation. Thanks for identifying 1067-exegnu-userdefaults, line 48 .. I expect that was once correct but maybe got changed in ascii/beowulf.. Not sure what you mean by modifications to the various refracta/live/exegnu-packages .. if you mean package lists, you would need to generate a new one before running refractasnapshot e.g. dpkg -l|egrep "^ii|^hi"|awk '{print $2 " " $3}' |column -t > pacckages.txt and place it manually in /live of your snapshot build directory before you build the iso.. Cheers, D

Hi David! I found that "lang=de locales=de_DE.UTF-8" thingie when I went through your code - well, after I patched the default language to de_DE. I decided it's better to keep the locals of my audience as default and did not revert the patches :) /etc/snapshotid: Found that, too. Uncommenting exegnu-installer line 36 solved that problem. Other tweaks I did was to keep autologin (exegnu-installer), basicly got rid of /etc/exegnu/skel (does not fit into my intended usecase) and placed all the defaults in /etc/skel. I remember I did some patching on the way for post-install changes of the homedirectory when the new username does not match the old - I hope i did not patch that out later .. I moved /tmp and /var/tmp to tmpfs, for the sake of flash livetime. I was thinking of doing that for /var/log, too, but then .. well, maybe later.
