[arch-general] unionfs or aufs, available somewhere?
Is either of them easily available somewhere? I'd like to use the `union-type=` option of `schroot`, but so far it looks like I'll have to get a new kernel from AUR and compile aufs3 myself to set it up. Is neither of these rather useful filesystems available pre-built somewhere? /M -- Magnus Therning OpenPGP: 0xAB4DFBA4 email: mag...@therning.org jabber: mag...@therning.org twitter: magthe http://therning.org/magnus

Is neither of these rather useful filesystems available pre-built somewhere? None of these filesystems work with an unpatched kernel. None of these are particularly fast or stable. None of these keep up well with current Linux development. The new and shiny overlayfs has still not been merged into 3.2 and union mounts development has stalled for a long time. It is 2012 now and the whole situation still sucks. We switched to (block-based) device mapper snapshots in archiso, which is stable, but far from optimal. This does not completely replace unioning and is likely not a good solution to use with schroot. signature.asc Description: OpenPGP digital signature
