Goal
One installation of overo-oe that all team-members can have read-write access to.
Installation
The acl tools package
sudo apt-get install acl
This contains
acl
getfacl
setfacl
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
