The sysvinit scripts require LSB headers on Debian/Devuan. The drop of LSB by Debian refers to not complying with the whole LSB specification which dictates far more than just the init scripts. There is nothing to prevent from defining different states at different runlevels. There is no practical way of determining what will be required at system build time by a generic installation utility, it is up to the system administrator to customise the install appropriately after. man update-rc.d publickey - g4sra@protonmail.com - 0x42E94623.asc Description: application/pgp-keys signature.asc Description: OpenPGP digital signature ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

No, Debian has had identical runlevels 2-5 for many releases, nothing to do with systemd. > Can I obtain a devuan different more clever system with update-rc.d ? I'm not quite sure what you're looking for - I've never tried Debian Buster, but Devuan Beowulf works fine for me, and I happened yesterday to have to install a sysvinit startup file (for zoneminder, which no longer comes with one by default), which got installed using update-rc.d without any problem. > https://en.wikipedia.org/wiki/Runlevel#Linux_Standard_Base_specification > devuan (beowulf standard installation with some cruft maybe) as I have it > on my notebooks does not conform to the LSB. Devuan is based on Debian, and that project dropped LSB support in 2015: https://wiki.debian.org/LSB You can have LSB, or you can have Debian/Devuan, but it's not easy to have both.

[DNG] Upgrade from buster to beowulf, runlevels are goofed
Hi Now I upgraded my other notebook from buster to beowulf. No more debian systems chez moi. I followed the advice from the website. However, the upgrades of the notebooks were not smooth. On the 2nd NB when I started the system after the dist-upgrade, it went straight into the Xserver. Only the xserver keyboard driver was lost in the process of upgrading. Only the power button on the NB could save, no, delete the situation. After changing /etc/rc2.d/S04lightdm to /etc/rc2.d/_S04lightdm I could safely boot and do the missing work. In the times of SuSE 7.0 to 7.3 I used runlevels to control a server with attached thin clients. The users on the system got a wall message and had to save their work. After a few minutes the runlevel was reduced from 5 to 3. This stopped the x client on the server, while maintaining the network connection. A backup was made, and when finished, the runlevel was increased to 5 and the thin clients (with a blank screen) obtained their login screen automagically again. It was extremely simple to accomplish. Since the times of SuSE7.3, after with I switched to debian in 2003, I did not observe the sysvinit/runlevels, there was no need to, until I obtained the systemd message: A service required was not available at start. Now I find that the runlevels are identical from 2 to 5 as opposed to the old times, when they were substantially differentiated. (root only, +local multi-user, +network, +Xserver) Is this a heritage of the debian distribution crippled by the poeystemd? Can I obtain a devuan different more clever system with update-rc.d ? https://debianforum.de/forum/viewtopic.php?t=173006 https://de.wikipedia.org/wiki/Runlevel#Beispiel_Linux https://en.wikipedia.org/wiki/Runlevel#Linux_Standard_Base_specification devuan (beowulf standard installation with some cruft maybe) as I have it on my notebooks does not conform to the LSB. Before filing a bug, I ask for the opinion here in the forum. -- mit freundlichen Grüßen with the beste regards cordialement Erich |\/|inderlei|\| -- ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
