Package: vmtouch
Version: 1.3.1-2
Severity: important
looking at the cmdline arguments the service actually provides to vmtouch it is
mangling the provided ones and thereby creates invalid arguments.
esp. for "-p 0-50k" which becomes "-p 0 50" and "-P /run/vmtouch" which somehow
gets joined together with the first provided item to cache.
`cat /etc/default/vmtouch`:
```

# User and group to run as

# Whitespace separated list of files and directories for vmtouch to operate on
VMTOUCH_FILES="/folder001/ /folder002/ /folder003/ /folder004/ /folder005/

# Options to pass to vmtouch itself. See vmtouch(8).
VMTOUCH_OPTIONS="-d -L -p 0-50k -f -P /run/vmtouch.pid"

Description: Portable file system cache diagnostics and control
vmtouch is a tool for learning about and controlling the file system cache of
unix and unix-like systems. It can discover which files the OS is caching, tell
the OS to cache or evict some files or regions of files, lock files into memory
so the OS won't evict them, and more.
