Which directories, and how, can I share between FreeBSD and Linux? In particular, how can I deduplicate respectively /usr/home and /home? I guess directly sharing a partition between both systems could lead to conflicting dotfiles, so that may not be the right solution. Is union-mounting the shared partition reasonable? This way, I could move the dotfiles into the "/" partition of each OS, and share the rest of the files into the shared partition.
Which filesystem should I use for the shared home partition itself? I have under 2GB RAM so I don't think ZFS will behave, from what I've read. Maybe ext2 will do? Any better options? EDIT: is write-to-UFS kernel support in Linux stable already?
- Linux distro is LMDE.
- Actually using PC-BSD but as far as I've read it should behave just as FreeBSD for this. Correct me if I'm wrong.
- Partitions would be:
OS Mountpoint FS Size (GiB; Total:~160GB) Linux / ext4 16 FreeBSD / ufs 16 Shared /mnt/home/ ext2? ~124 # EDITED: See below Shared - swap 4
Any other partitions I should make? It's a workstation without "persistent" servers, but I may fool around with jails in FreeBSD. Maybe I should have a partition for those?
Disclaimer: I haven't actually used union filesystems before, and am new to BSD in general; feel free to propose better solutions :)
EDIT: How about adding a "dotfiles" tree in each root partition and union-mount it?
Mount points in FreeBSD: / /mnt/home/ /usr/home/: /usr/dotfiles/ U /mnt/home/ # /usr/dotfiles/ has priority Example contents: /usr/dotfiles/fchurca/: .cache .kderc /mnt/home/fchurca/: .vimrc development/ Documents/ # .vimrc isn't platform-specific /usr/home/fchurca: .cache .kderc .vimrc development/ Documents/
This way, it could work for all the (two at most) users of the box.
