Suppress a pacman hook? virtualbox-host-dkms related [SOLVED]

graysky · 2016-03-06 17:27:49

Long story short, I am unable to build a custom package virtualbox-modules-custom which I have adapted to run on my own kernel since virtualbox-host-dkms runs the a hook that automatically builds the module that my PKGBUILD supplies. Is there a way I can have pacman skip running this hook as I try to work through this? My goal is to continue building my virtualbox-modules-custom package without simply using the dkms package. Thanks!

...or perhaps the problem lies with my PKGBUILD? Here is what happens when I attempt to build it post pacman-5.0.x:

Hooks can be overridden by placing a matching hookname.hook in a later HookDir (e.g. the default pacman..conf HookDir /etc/pacman.d/hooks/ will override the builtin /usr/share/libalpm/hooks/).

A symlink to /dev/null will disable the hook. (See `man alpm-hooks` under "Overriding Hooks".)

@Eschwatrz - Thanks for that info... upon looking closer I am unable to see in the virtualbox-host-dkms PKGBUILD that pacman is even asked to call a hook, yet:

...
(2/2) installing virtualbox-host-dkms                                        [############################################] 100%

    linux-headers
    linux-lts-headers
:: Running post-transaction hooks...

Further, I have no dir /etc/pacman.d/hooks and /usr/share/libalpm/hooks which does exist on my filesystem is empty.

eschwartz · 2016-03-06 17:51:16

That's odd, because the "dkms" package provides the files "/usr/share/libalpm/hooks/70-dkms-install.hook" and "/usr/share/libalpm/hooks/70-dkms-remove.hook". And "virtualbox-host-dkms" depends on "dkms"...

As for /etc/pacman.d/hooks, you will have to create it manually if you want to use it.

@E - Ah! The makedeps was removed when I checked.... I got it working with the /dev/null symlinks. Thanks!

% ls -l /etc/pacman.d/hooks
total 0
lrwxrwxrwx 1 root root 9 Mar  6 13:29 70-dkms-install.hook -> /dev/null
lrwxrwxrwx 1 root root 9 Mar  6 13:29 70-dkms-remove.hook -> /dev/null

For someone else finding this thread in the future, I also needed to modify the PKGBUILD since now, dkms expects the source to be under:
/usr/src/5.0.14_OSE rather than /usr/src/5.0.14

Link to the new functional PKGBUILD.
