[ Reason ] With exfatprogs 1.2.6 mkfs.exfat was changed to handle devices with 4KB sector size but a 512Byte sector size emulation as a 4KB sector size device for performance reasons. https://github.com/exfatprogs/exfatprogs/commit/f47362d4d62422be0b3823f1e50f0b4cd62b265 That turned out to be incompatible with Windows and was reverted in https://github.com/exfatprogs/exfatprogs/commit/d4f77ae41ce178c04b8e3326178554182ca94bd5 and released as part of exfatprogs 1.3.0. That issue was brought to my attention via https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1120932 that the default "mkfs.exfat" invocation on Debian/trixie formats such a device in a way that is incompatible with Windows. [ Impact ] Devices with a physical 4KB sector size exposing an emulated 512Byte sector size get by default formated in a way that is unusable for Windows. [ Tests ] Since this household no longer has any Windows operated devices I've a hard time replicating the issue and testing the remediation. [ Risks ] Since upstream decided to revert that change and the bug reporter suggested that this change fixes his issue, I think it's ok. Users will likely see a performance degradation on those devices meeting the criteria leading to the original bug report. [ Changes ] * Add trixie branch information to gbp.conf and Vcs-Git. * Add debian/patches/windows-compat-use-512-sector-size.patch for Windows compatibility. Windows fails to access devices with a 4KB sector size which use a 512Byte sector emulation. Cherry-Pick the revert from exfatprogs 1.3.0 to use a 512Byte sector size for those devices, despite the performance penalty. If a user would like to omit the Windows compatability "mkfs.exfat -s 4096" can still be used to override the sector size.
