7.2 Known Issues with dazukofs

Mounting dazukofs

It is highly recommended to mount dazukofs very early during system startup,

via /etc/fstab, for optimum functionality and protection.

It is not recommended to unmount dazukofs, once loaded.

For more details, please refer to the dazukofs documentation:

http://dazuko.dnsalias.org/files/README-dazukofs

Mounting removable media

Removable media such as USB-sticks and CD-ROMs should be automatically mounted.

Else:

- If the media is not mounted via dazukofs, it is not protected;

- If it is mounted via dazukofs, you cannot unmount the media without unmounting

dazukofs first (which can break some applications).

Scanning on-access: symlinks

Please note how dazukofs handles symlinks: In case a folder is mounted as dazukofs and a

file (file.a) within that folder is a symbolic link to another file (which is not in a folder

mounted as dazukofs, for example file.b), access to file.a is always granted, while file.b is

not scanned, since it is not accessed through dazukofs.

Unsupported system calls

Dazukofs currently does not support the sendfile() system call.

This may lead to problems if you want to use dazukofs in conjunction with applications

that rely on sendfile(), as for example apache servers.

If you want to use dazukofs to protect the document root dir of an apache server, add the

following line to the httpd.conf:

EnableSendfile Off

</Directory>
