Sdef and 'commands'

#1

Hiya,

When a ‘command’ is defined in an sdef file, at runtime does Legato copy the binary to the filesystem, or does Legato symlink the binary into the filesystem?

ta, Dave

Hi @davidc,
if i have understood your question correctly, Binary/executable will be present in the application’s directory/file system which are mentioned in the ‘commands’ section of .sdef file and symlink of these binaries/executables will be used from the directory ‘/mnt/legato/system/bin’ to use the respective command.

Below is an example where all the binaries/excecutables of the application ‘tools’ which are mentioned in the ‘commands’ section of .sdef and symlinks of these binaries/excecutables are used in the ‘/mnt/legato/system/bin’ directory. Hope your doubt is clear.
