[Home] Sharing project files with a team using ACLs on Ubuntu


One installation of overo-oe that all team-members can have read-write access to.


The acl tools package

sudo apt-get install acl

This contains


The gui acl package for nautilus

sudo apt-get install eiciel

Mounting with ACLs

Modify the / or /home partition (or wherever) to include ACL support

vim /etc/fstab

Just add acl after defaults

# /home was on /dev/sda5 during installation
UUID=488cd15e-8d2a-45e2-9ed0-00f9643e8cf2 /home           ext3    defaults,acl        0       2    

And then remount

sudo mount /home -o remount

Setting up a shared location

To keep things simple I create a directory /home/shared, owned by root and give all users rwx by default.

This means that any new file or directory created within this directory wil have rwx.

setfacl --physical --set default:other::rwx /home/shared/
# or in a more sensitive environment
# setfacl --recursive --set u:harry:rwx /home/shared

The caveat is that files copied or moved will have the same permission that they previously had. They will not get updated.

cd ~/
mv overo-oe/tmp /home/shared/overo-oe-tmp
ln -s /home/shared/overo-oe-tmp overo-oe/tmp
setfacl --recursive --set default:other::rwx /home/shared/overo-oe-tmp
