Hello Everyone,

In CentOS 6 x64 ploop environment, may you please suggest how to mount the /tmp securely? (i.e. nodev, nosuid, noexec)

Thank you very much for your kind advice.

Regards
George

Hi,

I mount my ext4 /vz partition for ploop containers with below options:

tune2fs -o journal_data_writeback /dev/sdXY
Where /dev/sdXY is replaced by the partition that you actually use

Then in /etc/fstab i put

noatime,data=writeback,barrier=0,nobh,errors=remount-ro        0 1

for host /tmp I don't use separate partition.

It isn't any different than simfs. Use tmpfs or bind.
