[arch-general] Is it a bug ? (device-mapper PKGBUILD)

[nezmer]

Hi ,
I was looking at the device-mapper PKGBUILD . I'm not sure but the last 
line looks problematic :

# fix device-mapper link bug
ln -sf /lib/libdevmapper.so ${pkgdir}/usr/lib/libdevmapper.so || return 1

What If device-mapper is not yet installed in the system ?
What am I missing ?

if i understand it correctly, build() just builds the package.  only
when you pacman -U it will you execute those commands (in sequence).

therefore, the make and install steps are exectuted before the symlink
is created.

 There will be a symlink in /usr/lib/libdevmapper.so that links
 to /lib/libdevmapper.so, whether this file exists or not. When the
 package is installed, this file exists because it is included inside the
 package.
 
aha .
Lesson of the day : We can link non-existing files .

Thank you for the clarification .
