The cache_dir line only provides the sd->path, sd->max_size, sd->u.ufs.l1
and sd->u.ufs.l2, where sd = Config.cacheSwap.swapDirs[i]. But how is the
cacheSwap struct (swapDirs, n_allocated & n_configured) initialized?

In other words, in the function storeUfsDirParse(), do you always call
allocate_new_swapdir() ? (That would happen if swap->n_configured is zero).

storeUnlink() calls storeUfsUnlink(), which in turn, calls unlinkdUnlink().
This whole routine is bounded by #if USE_UNLINKD. Is USE_UNLINKD *always*
defined?

Thanks for your help,
