Detailed Description

Crafted ._ sidecars are opened through ad_open() with resource-fork write intent, mirroring the afpd call sequence. Malformed entries must be rejected with errno EIO and leave the sidecar untouched. A well-formed sidecar must be rewritten to the canonical OS X layout with its resource fork payload preserved byte for byte.

Find a suitable temporary directory for Netatalk.

Creates a subdirectory for current gid if it doesn't exist. The result should be copied immediately as it may be overwritten by a subsequent call.
