I would like to have FlashCache cache my /var partition however I can't seem to get it to play nice upon bootup (IE: not really sure how to do it).

I'm not sure if I need to modify the initramfs/use DKMS or if I can do it in user-land during bootup. The issue I'm running into is /var mounts early and therefore the device is busy (whether it by generally by syslogd).

I'm positive this can be resolved by modifying the initramfs although I simply haven't fiddled with it enough to get it working.

They have instructions on how to boot your root partition however I'm not sure if these instructions would apply to my use case.

Any help / pointers in the right direction would be absolutely splendid.
