[Pkg-zfsonlinux-devel] Bug#903112: Waits for spl build directory

[Yuri D'Elia]

Package: zfs-dkms
Version: 0.7.9-3
Severity: normal

If the spl module builds fails, the zfs configure scripts does a
pointless wait loop during "configure":

...
configure:14082: checking spl source directory
configure:14140: result: /usr/src/spl-0.7.9
configure:14154: checking spl build directory

I don't get it: why is this even necessary?
There seems to be some specific logic about this in the configure
script:

  --with-spl-timeout=SECS

This is causing waits in orders of tens of minutes during package
installation if the spl build fails, since dkms is triggering a rebuild
multiple times.
