Source: debian-installer-utils Version: 1.147 Severity: normal I'm hacking together an installer for an rpi4 locally, copying all the files onto a FAT-formatted USB drive. I also want to do some minor config in a preseed late_command, so I've modified the initrd to add a preseed file.
Unfortunately, once I added the preseed file d-i fails in cdrom-detect. Digging further, I've found that this is because the USB drive is already mounted on /media. This is caused by the "fetch-url" command in preseed/preseed_fetch. In fetch-url-methods/file, we call mountmedia to allow for preseed via USB from netboot - see commit 916a613577c5cd747d15b3d20f16b9518d7d54ea in 2013!! This mountmedia is not needed in my case, and is what's breaking things. As a workaround, I've added a preseed early_command for now to *unmount* /media and all is well. But this code needs changing to not run mountmedia unconditionally! We already had a report from Bogdan Veringioiu about this problem back in 2018... :-( [1] [1] https://lists.debian.org/debian-boot/2018/04/msg00057.html -- System Information: Debian Release: 11.7 APT prefers oldstable-updates APT policy: (500, 'oldstable-updates'), (500, 'oldstable-security'), (500, 'oldoldstable'), (500, 'oldstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.10.0-23-amd64 (SMP w/8 CPU threads) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8), LANGUAGE=en_GB:en Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled
