Steps to reproduce:

1. Create test directories:

   mkdir -p /tmp/{test,test-1,test-2}
   

2. Inside /tmp/test, create symlinks:

   cd /tmp/test; ln -s ../test-1 1; ln -s ../test-2 2; ln -s 2 current
   

3. Get the directory listing with vfs.dir.get, i.e.:

zabbix_agentd -t 'vfs.dir.get[/tmp/test]' | awk '{print $2}' | sed -e 's/^...//' -e 's/.$//' | jq .[].basename

Result:

vfs.dir.get resolves the current symlink and returns information about its target:

"test-2"
"test-1"
"test-2"

Expected:

"current"
"test-1"
"test-2"

vfs.file.get[/tmp/test/current] also returns information about test-2. There is no way to find out what current points to.
