That suggestion inspired an apt-cache search: apt-cache search kernel filesystem doc Which brought up two docs appropriate for my own Trixie setup: linux-doc-6.5 and linux-doc-6.6. The description for 6.6 is: Description-en: Linux kernel specific documentation for version 6.6 This package provides the various README files and HTML documentation for the Linux kernel version 6.6. Plenty of information, including the descriptions of various kernel subsystems, filesystems, driver-specific notes and the like. An index to the documentation is installed as /usr/share/doc/linux-doc-6.6/html/index.html. Sounds pretty good, in fact just downloaded for myself. For those who haven't found them yet, you can also install various Debian centric handbooks using similar searches, e.g. for "admin". Empowered users, yada-yada!
