Package: release-notes Severity: normal It has been a long time since late-mounting /usr (ie, using only tools in /) has been actually supported. In stretch, all initramfs generators mount /usr if it is a separate mount, so that init receives both / and /usr mounted.
Problems can occur if /usr is not pre-mounted due to: 1. Programs used during early boot require libraries or other files in /usr. (Example, #829127) 2. Udev rules might be invoked very early in the boot process, causing programs from /usr to be executed. (Example udev rules, 90-alsa-restore.rules, 63-md-raid-arrays.rules, 39-usbmuxd.rules). What does this mean for users? It means that if (1) you have /usr on its own partition, and (2) you do not use an initramfs; then you should start using one. All of the debian-provided initramfs generators will generate a suitable one. The release notes should document this requirement. -- System Information: Debian Release: stretch/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'unstable'), (1, 'experimental-debug') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.6.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_GB.utf8, LC_CTYPE=en_GB.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system)
