If there is write permission, it just creates a + standard file using "creat()" and therefore, uses the IMFS MEMORY_FILE. + If there is no write permission, it creates a LINEAR_FILE node + with the appropriate properties. If the permission is ever changed + to writeable, IMFS_fchmod converts it to a regular memory file. + +2000-12-12 Jake Janovetz + + * src/imfs/linearfile.c, src/imfs/imfs_load_tar.c: New files. + * src/imfs/Makefile.am, src/imfs/imfs.h, + src/imfs/imfs_creat.c, src/imfs/imfs_debug.c, + src/imfs/imfs_eval.c, src/imfs/imfs_handlers_memfile.c, + src/imfs/imfs_init.c, src/imfs/imfs_initsupp.c, + src/imfs/imfs_stat.c, src/imfs/miniimfs_init.c: Added "tarfs". + This is not really a tar filesystem.
