What's causing "/bin/sh: 1: folder2ram: not found"?

Hi

Building our OMV based little NAS.

Script Version: 0.2.0
Debian-Version: 7.10
OMV-Version: 2.2.2
openmediavault-flashmemory 1.9.2
zswap.enabled=1

Following keeps showing up in logs :

/bin/sh: 1: folder2ram: not found

Wondering whether anyone knows possible cause before fiddling in the source trying to get a clue and solve this. Thanks!

Hey, thanks for looking! Actually it is and seems to be doing fine --but the log line:

# which folder2ram
/sbin/folder2ram


# dpkg -l | grep folder2ram
ii  folder2ram                           0.1.5                          all          script-based utility that relocates the contents of a folder to RAM
ii  openmediavault-flashmemory           1.9.2                          all          folder2ram plugin for OpenMediaVault

Will `apt purge` and check again while I'm setting up the backup (means there's nothing valuable on the fs yet)

True. Started to show up only last night. Rebooted and that batch of a warning seems to be gone (btw it killed my email: "suspended"!)

Who told me I'd restart the NAS times more often than a new Arch Desktop, I'd have laugh at his face, errr

EDIT: no more warning log since reboot last night. Thank you subzero79! Changed to SOLVED.

Back with

/bin/sh: 1: folder2ram: not found

I checked upon the last two reboots: Happens each time I sync tmpfs dirs to disk using cron, ie:

33 */1 *   *    * folder2ram -syncall

Same action from a Bash shell reports no errors or warning.

Thank you subzero79 for reminding me I'm only second to cron when it comes to taking environment variables in account ;-/
Seriously, appreciated.
