The findmount and lsblk utilities need udev to work correctly but cannot
be built with udev support because the packages providing libudev (eudev
and systemd) depend on util-linux, creating a chicken-egg problem. Solve
it by means of the following changes:
- Split util-linux into three packages:
- util-linux-libs, providing lib{blkid,fdisk,mount,smartcols,uuid}.
- util-linux-programs, providing both the aforementioned libs and the
programs.
- util-linux, a dummy package that drives configuration and building
of the other ones.
- Add blind selections for -libs and -programs, i.e. they are indirectly
selected according to the util-linux options.
- Make util-linux have build dependencies on util-linux-{libs,programs}
if they are selected.
- host-util-linux has a build dependency on either host-util-linux-libs
or host-util-linux-programs (not on both, since they are installed on
the same destination).
- Make eudev and systemd have build dependencies on util-linux-libs.
This can be extended to other packages in the future but is not needed
right now because the configuration options are backward-compatible.
- Make util-linux-programs have an optional build dependency on the
package that provides libudev (either eudev or systemd), if it is
selected.
util-linux-libs is installed on STAGING_DIR by default and on TARGET_DIR
if util-linux-programs is not selected. Conversely, util-linux-programs
installs on TARGET_DIR by default and on STAGING_DIR if util-linux-libs
is not selected. This prevents installing the libraries twice on the
same destination, which would confuse check-uniq-files.
With this approach we don't need to patch configuration files neither
change other packages besides eudev and systemd. Other packages that
require util-linux libraries and whose libraries can be used by
util-linux programs can be updated later. We also don't need to change
any existing defcconfig, since all configuration options are kept in
the dummy util-linux package.
The main drawback of this approach is that util-linux-rebuild, as wel as
-reinstall, -reconfigure and even -dirclean targets do not have real
effect. It's necessary to use util-linux-libs-rebuild, for instance, but
this is a reasonable price to pay for the solution.
