Re: [Gnu-arch-users] Need to version control entire root file system

[Ben West]

Hypothetically, you could mount another file system over root using union-fs and see that the arch meta-data lived in the mounted version instead of the original (e.g. the arch meta-files would exist in a ghost directory somewhere, pehaps, less visible to the system.

you would mount root as usual 
in a subdirectroy, you would remount root (readonly)
then mount another arch-metadata directory over top (writeable)
so that any changes to the metadata would be written to the seocnd directory -- then for updates/syncs, etc you would sync/update the union file system

I'd consider reading up on unionfs to see if this will work for you.  


Also, I think the latest version of reiser supports version control build in.

The base "image" is kept offline.  I want to version control changes to
every file and directory in that offline image.

Ascii files need explicit diffs, binary files can just be flagged as
changed.  I need to be able to view which files changed at any check-in
point, what files are different now from the last check-in, how the
ASCII files changed between any two versions, and roll-back the entire
image to any previous version.

Mostly, I need the diff repository to be outside the image; I don't want
hidden version control directories in every directory of my file
system... I need the version control meta-data kept elsewhere (this
image gets provisioned onto systems).

Will Arch do this?  If not, can anybody recommend a good version control
utility (or maybe one that is extensible) for this?

Note that I use "image" to mean "root file system", and not a disk image
per se; something you could chroot to.

Thanks,

Chris
