Welcome back copytoram= option
Fixes FS#17182: copytoram=y does not work with aufs The solution is simple, just use a directory outside aufs tree. * If copytoram=y, then another tmpfs is mounted but on /tmpfs.sqfs * Add a new option: tmpfs_sqfs_size= (default to 75%) * Lock cdrom drive is not locked if copytoram=y Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>
