Default $work_dir is not passed through realpath
After 183ae527, _make_customize_airootfs()
fails if the working directory is not set with the -w
option since the default $work_dir
is only a directory name which makes it a relative path.
The default values of $work_dir
and $out_dir
should be resolved with realpath
as various parts of mkarchiso rely on them being an absolute path.
