Package: dkms
Version: 3.0.11-3
Severity: normal
Hi,
I have computers where I install both zfs-dkms and sometimes
zfs-modules-<someversion> packages.
When zfs-modules-<someversion> is installed, zfs-dkms fails postinst:
[...]
zzstd.ko:
Running module version sanity check.
Module version 1.4.5a-2.1.12-2 for zzstd.ko
exactly matches what is already found in kernel 6.4.0-3-amd64.
DKMS will not replace this module.
You may override by specifying --force.
Error! Installation aborted.
dpkg: error processing package zfs-dkms (--configure):
installed zfs-dkms package post-installation script subprocess returned error
exit status 6
I think that when all modules to be installed exactly match the ones already in
place, that shouldn't result in a failure.
In case you wonder why I'm doing this: these computers take forever to build
kernel modules, so whenever possible, I install pre-built modules and want to
keep dkms only as a failsafe, to make sure the zfs modules are in place before
I reboot (because they're needed for booting).
I'm filing the bugreport against dkms because it contains these lines of code
(around line 800):
if [[ ! "$force" ]]; then
# if the module has neither version nor srcversion/checksum, check
the binary files instead
local verinfo="$(get_module_verinfo "${dkms_module}")"
if [[ "$(echo "$verinfo" | tr -d '[:space:]')" ]] || diff
"${kernels_module}" "${dkms_module}" &>/dev/null; then
echo $"Module version $(echo "$verinfo" | head -n 1) for
$4${module_suffix}" >&2
echo $"exactly matches what is already found in kernel $1." >&2
echo $"DKMS will not replace this module." >&2
echo $"You may override by specifying --force." >&2
return 1
fi
fi
I believe that "return 1" should be a "return 0" because there is no failure. A
binary with the exact same version and/or contents is already installed; that's
exactly the outcome dkms was asked to achieve.
I'll file a separate bug against zfs-dkms asking to avoid building the module
for kernels for which an appropriate zfs-modules-<version> package is installed.
