Hi,
I'm a developer of Chakra Linux and I'm analyzing the pros and cons to switch
our bundle system from unionfs to aufs.
Maybe first a short description of what a bundle is: Chakra is kde-centric
distribution, was decided to don't provide the gtk applications as package but
only in the form of bundle. A Bundle is a squash file system with all the
dependencies on it that is mounted on request. Currently the bundles are
mounted in /tmp/ and in some case (like chrome) a chroot+unionfs is need.
The main idea is to improve what we have already by mounting the bundles
directly over / in a new aufs branch. The advantages are that we don't need
anymore a chroot and the users can easily use local system-wide installed
plugins.
I would like to know what do you think about this points below based on your
experience:
- mounting on / is a good approach on a real system? (not a livecd where is
used mostly)
- what about the read/write speed on the HD if the root is mounted with aufs?
can decrease if many branches are added?
- use aufs without remount / (is already mounted at boot) is possible?
something like "mount -t aufs -o dirs=/=rw none /" make sense?
If you have other proposals or some special mount options that permits to
archive our idea please let me know.
Thanks,
Luca
