[lxc-users] lxc-users Digest, Vol 233, Issue 11

[Thouraya TH]

 Thank you for answer.
Example
lxc-create -n c1 -o ubuntu
i don't mean ubuntu image

I mean these files:

Example:

root at graphene-14:/var/lib/lxc/graphene-14-worker1# ls

config  fstab  rootfs


These folders content
config  fstab  rootfs are the same for the three containers on the same
host ?
it's up to me to use a deduplication solution  ? That's it ?
Bests.
