Oops ... good catch. Trying to be less greedy now ...

That must have happened in my module build chroot, too, but I probably 
blamed the zfs failure to an existing bug about lacking support for the 
most recent kernel ... and it was gone after zfs got updated.
(And it wouldn't reappear since that is a one-shot cleanup done by 
dkms.postinst.)

Bug#1059900: Postinst deletes module source files

[Petr Čech]

Package: dkms
Version: 3.0.12-3
Severity: important

Hi,
after upgrading the postinst tries to delete old source files. It seems
that it is a bit too liberal and removes also source files from zfs as
it contains /module/ directory. It renders zfs module unbuildable with
next kernel upgrade.


Installing new version of config file /etc/kernel/postinst.d/dkms ...   
removed '/var/lib/dkms/zfs/2.2.2/source/module/zstd/zfs_zstd.c' 
   
removed '/var/lib/dkms/zfs/2.2.2/source/module/zstd/lib/zstd.h'
...
removed directory
'/var/lib/dkms/zfs/2.2.2/source/module/icp/algs/blake3' 

removed directory '/var/lib/dkms/zfs/2.2.2/source/module/icp/algs'  
  
removed directory '/var/lib/dkms/zfs/2.2.2/source/module/icp'   
  
removed directory '/var/lib/dkms/zfs/2.2.2/source/module/'


Regards,
Petr
