you'll likely need -rf or rmdir here? any reason not to keep the test as is? that way no errors are thrown if the directory does not exist I think...

also the previous test -h unlinked and relinked the pkg_pre_download dir so that if it changes the script works?

So here was the problem i hit...basically if you have previously tried to download packages (which creates a pkg dir) then want to enable the shared dir it fails:

ahulbert@nuc16:/tmp/cloud-local$ bin/cloud-local.sh init
rm: cannot remove '/tmp/cloud-local/pkg': Is a directory
ln: failed to create symbolic link '/tmp/cloud-local/pkg/packages': File exists

I was thinking that block could remove the existing pkg dir if it exists and then link in the shared dir?

My feeling is primarily that the user should decide what they want to do with the contents of the existing folder... e.g. copy into synology? just plain delete? rename to folder to keep as other stuff?

yeah that sounds like a good idea. Lets not do an RM at all then? we can instead just set a variable to be the pkg dir and pull stuff out of there? That would require making something new like setting a cl_pkg_dir that if the pre download is not set would become ${CLOUD_HOME}/pkg ? that way we don't remove anything and just use the new dir as is and no symlinks. nothing to delete/remove

so by default if you had a ${CLOUD_HOME}/pkg dir and then enable the pkg_pre_download it just leaves the existing pkg dir there i guess

ln -s ${pkg_pre_download} ${CLOUD_HOME}/pkg
echo "Skipping downloads... using ${pkg_pre_download}"
return 0
